If we are moving in snap mode (shift pressed) we don't want to tile. We must
also cancel any pending tiling if snap mode is activated during the move drag.
https://bugzilla.gnome.org/show_bug.cgi?id=662270
When we reparent a window to the root when we're exiting, we need to offset
the position by the invisible borders, otherwise windows will creep up and
to the left.
https://bugzilla.gnome.org/show_bug.cgi?id=660848
meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642580
When using more than one monitor, tiled maximization can be triggered with the
pointer in one monitor while most of the window area remains in another. This
means that the maximization constraint would maximize the window into the wrong
monitor as it uses the work area size/position as target.
Fix this by using the current tile area as target size/position.
https://bugzilla.gnome.org/show_bug.cgi?id=657519
Since the frame window size that meta_window_move_resize() uses depends
on whether the window has horizontal/vertical resize functionality, we
need to update this flag before we resize the window.
https://bugzilla.gnome.org/show_bug.cgi?id=659854
If a window had a type hint intended for override-redirect windows
like NOTIFICATION, we ended up with a window that was decorated but
with a frame type of FRAME_TYPE_LAST, causing assertion failures.
Fix this by making recalc_window_features() just call
meta_window_get_frame_type().
https://bugzilla.gnome.org/show_bug.cgi?id=599988
The theme state used to use GtkStateType, but was ported over to GtkStateFlags,
leaving behind a broken assertion that fails when using certain Metacity
themes, for example Nodoka.
https://bugzilla.gnome.org/show_bug.cgi?id=661286
_NET_FRAME_EXTENTS should contain the difference between where a window asked
to be placed, and where it is. Ideally, this should be the same as the visible
extents.
https://bugzilla.gnome.org/show_bug.cgi?id=659848
A window can specify geometry that it is placed at. We need to exclude invisible
borders when calculating where to place the window, otherwise the window will have
a strange offset.
https://bugzilla.gnome.org/show_bug.cgi?id=659848
When a window loses its frame we must unset any overlay path previously set on
the shaped texture.
Not doing so would cause rendering glitches near the window corners in
e.g. chrome/chromium by changing the Appearance preference "Use system title
bar and borders" → "Hide system title bar and use compact borders".
https://bugzilla.gnome.org/show_bug.cgi?id=659477
Shaded windows are assumed to be reduced to the titlebar: the
current code enforces a visible bottom border of 0 and only takes
the size of the title bar (+ invisible top border) into account
when resizing the frame. However, we still add an invisible border
at the bottom, which is than subtracted from the title bar, resulting
in shaded windows being cut off.
Fix by forcing both visible and invisible bottom borders to 0.
https://bugzilla.gnome.org/show_bug.cgi?id=659266
XFixesCreateRegionFromWindow does not take the window's position into account,
which results into setting a wrong shape for windows not located on the
leftmost monitor.
Fix that by creating the region from the window's MetaRectangle.
https://bugzilla.gnome.org/show_bug.cgi?id=657869
If we do this, then there will be invisible borders around the top of attached
modal dialogs, which is unnecessary -- they can't be resized from the top
border and just interfere with the parent dialog.
This requires changing a bit of API to help identify the type of dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=657795
Our usage of DamageReportBoundingBox was causing us to miss some
updates when an area of the screen was drawn twice in rapid
succession. Add an explicit XSync() call to force the server
to flush rendering to the kernel before we draw.
https://bugzilla.gnome.org/show_bug.cgi?id=657071
If XRANDR is availible, we track the first (or primary) output per
crtc (== xinerama monitor) so when the monitors change we can try
to find the same output and move windows there. If we can't find the
original monitor in the new set (or XRANDR is not supported) we move
the window to the primary monitor.

The ignored_serials member of Display refers explicitly to crossing
serials - rename the member and associated functions and constants
for clarity.
https://bugzilla.gnome.org/show_bug.cgi?id=597190
* Export meta_display_add_ignored_crossing_serial()
* Add the serial for reshaping the stage
* Increase the size of the "ignored_serials" array a bit to
try to avoid the possibility of losing serials from multiple
reshapes happening close together.
https://bugzilla.gnome.org/show_bug.cgi?id=597190
This goes better with the general style of similar alerts throughout
GNOME 3, and as has been pointed out in bug 591735, 'Mutter' is
a somewhat unfortunate title in several lanuages, such as English
and German.
* At least one line (possibly blank) is required after a function name for a doc header
to be parsed correctly.
* SnStartupSequence isn't a type known to introspection
Some apps that do a lot of rendering on the screen like games, mostly run in
fullscreen where there is no need for them to be redirected doing so does add
an overhead; while performance is critical for those apps.
This can be disabled / enabled at runtime using
meta_enable_unredirect_for_screen / meta_disable_unredirect_for_screen
https://bugzilla.gnome.org/show_bug.cgi?id=597014
Instead of requiring a singleton MetaBackgroundActor for the screen,
allow creating multiple copies that internally share a single
CoglTexture behind the scenes. This will be useful for allowing
multiple views of the screen background with different rendering
options.
https://bugzilla.gnome.org/show_bug.cgi?id=656433
Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.
https://bugzilla.gnome.org/show_bug.cgi?id=646761
The code here was wrong in every way: it only updated the shape if all the
borders changed. It never saved new last_borders even if it *had* changed,
and the bounding rectangle's x and y positions were still important otherwise.
This had user-visible impact when doing simple things like changing the
border_width. It would short-circuit here and due to the above incorrectness,
weirdness could happen where windows would be cut off and so on.
https://bugzilla.gnome.org/show_bug.cgi?id=656334
gtk:custom() requires a fallback color in case the GTK+ theme in use
does not define the desired color. As in general the fallback color
will approximate the intended color, there is the risk of typos going
unnoticed. To make catching these kind of errors easier, allow to ignore
the fallback color specified (and fall back to a nice shade of pink
instead) by setting an environment variable.
https://bugzilla.gnome.org/show_bug.cgi?id=656112
get_outer_rect now returns the visible region, and a new get_input_rect
method returns the boundaries of the full frame, including the possible
invisible regions. When undecorated, both do the samething.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
Just a quick little commit to help clean things up for when we add invisible
borders. Additionally, do a little housekeeping in preview-widget as well.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
There were actually *two* MetaFrameGeometry structs: one in theme-private.h,
one in frame.h. The latter public struct was populated by a mix of (void*)
casting and int pointers, usually pulling directly from the data in the private
struct.
Remove the public struct, replace it with MetaFrameBorders and scrap all
the pointer hacks to populate it, instead relying on both structs being used
in common code.
This commit should be relatively straightforward, and it should not do any
tricky logic at all, just a sophisticated find and replace.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
Since we're not setting the frame's output shape any more, it doesn't
make sense to calculate the output shape based on the frame window.
Instead, track the client window directly and calculate the output shape
based on that.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
In preparation for switching to handling the output shape purely by what we
paint, stop applying a shape to the frame of the window. Even when we restore
handling the output shape, this will change the behavior with respect to input;
transparent areas between the frame and the contents will stop clicks rather
than passing them through, but that is arguably at least as expected
considering how that we decorate shaped windows with a frame all around.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
We were leaving some members of the button_layout struct uninitialized if the
pref string didn't have at least one colon or if it was an empty string ("").

MetaShapedTexture can be a ClutterX11TexturePixmap sub-class, given that
ClutterGLXTexturePixmap is just a shim compatibility layer since Clutter
1.4, and it's been deprecated.
https://bugzilla.gnome.org/show_bug.cgi?id=655064
meta-texture-rectangle and meta-shaped-texture both create textures
with GL_TEXTURE_RECTANGLE_ARB as the target using direct GL
calls. This patch moves that code into a shared utility function in a
separate file instead. The function resolves the required GL symbols
dynamically instead of linking to them directly so that if Clutter
eventually stops linking to -lGL mutter will continue to build. The
function also splits the texture creation into a separate texture
creation and data upload stage so that it can use
cogl_texture_set_region to upload the data. That way it can avoid
clobbering the glPixelStore state and it can let Cogl do any necessary
format conversion. The code preserves the old value of the rectangle
texture binding instead of clobbering it because Cogl expects to be
able to cache this value to avoid redundant glBindTexture
calls. Finally, the function uses cogl_object_set_data to
automatically destroy the GL texture when the Cogl texture is
destroyed. This avoids having to have special code to destroy the cogl
texture.
https://bugzilla.gnome.org/show_bug.cgi?id=654569
texture_tower_revalidate_fbo() called cogl_flush() to work around
clutter bug #2110, which has been long fixed.
As we depend on clutter 1.7.x anyway we can just remove that workaround.
https://bugzilla.gnome.org/show_bug.cgi?id=654729
Clutter now has some API to get the bounds of the current redraw clip
so Mutter no longer needs to make direct GL calls to get the scissor
rect. This should make it more robust against Cogl or Clutter changing
how it does the clipping.
https://bugzilla.gnome.org/show_bug.cgi?id=654551
Calling meta_later_add() or meta_later_remove() from within a
META_LATER_BEFORE_REDRAW callback ended up being a no-op, because of
how run_repaint_laters() was fiddling with the laters list. (This
resulted in a crash in window.c:idle_calc_repaint(), which assumed it
would only be called when a certain queue was non-empty, but was
getting called anyway because of a failed meta_later_remove() call.)
Fix this by having run_repaint_laters() work on a copy of the laters
list instead, and add refcounting to MetaLater so that removing a
later that run_repaint_laters() hasn't gotten to yet won't cause
problems.
https://bugzilla.gnome.org/show_bug.cgi?id=642957
When we get a press of the overlay key, and then another key is pressed,
first try to handle the combination as a global keybinding. If that fails,
call XAllowEvents(..., ReplayKeyboard, ...) to let it be handled by
our per-window keybindings or by the application.
This requires restructuring things to call XAllowEvents a bit later
so we can pass the right mode.
https://bugzilla.gnome.org/show_bug.cgi?id=624869
meta_frames_destroy() was not safe to be called multiple times, which
was causing a crash on exit due to something else changing somewhere
that makes it get called multiple times.

- menus have a very subtle shadow, define the outline better. Required for gtk theming.
- focused windows are better identified now as unfocused windows have a subtle shadow.
https://bugzilla.gnome.org/show_bug.cgi?id=649374
A x/y typo that was causing shadow bounds to be incorrectly
computed and trails to be left in some circumstances. Behavior
noted by Jakub Steiner.
https://bugzilla.gnome.org/show_bug.cgi?id=649374
The code assumed that the focus window was always the one at the
top of the window stack, which is not true if an unfocused window
has the above hint set.
Rather than fixing this assumption, rename the function to
lower_beneath_grab_window() and use the display's grab window - the
function is only used for displaying the tile previews, which means
that we want the grab window anyway.
