@ -27,7 +27,7 @@ On X11, Clutter depends on the following extensions
• XDamage
• XExt
• XFixes
• XInput 1.x (if --enable-xinput is passed to configure)
• XInput 1.x or 2.x
• XKB
When running the OpenGL flavor, Clutter requires at least version 1.3

*
* The problem stems from the fact that rectangles for the
* blits are described relative to the bottom left of the
* window and because we can't guarantee control over the X
* window gravity used when resizing so the gravity is
* typically NorthWest not SouthWest.
*
* This means if you grow a window vertically the server
* will make sure to place the old contents of the window
* at the top-left/north-west of your new larger window, but
* that may happen asynchronous to GLX preparing to do a
* blit specified relative to the bottom-left/south-west of
* the window (based on the old smaller window geometry).
*
* When the GLX issued blit finally happens relative to the
* new bottom of your window, the destination will have
* shifted relative to the top-left where all the pixels you
* care about are so it will result in a nasty artefact
* making resizing look very ugly!
*
* We can't currently fix this completely, in-part because
* the window manager tends to trample any gravity we might
* set. This workaround instead simply disables blits for a
* while if we are notified of any resizes happening so if
* the user is resizing a window via the window manager then
* they may see an artefact for one frame but then we will
* fallback to redrawing the full stage until the cooling
* off period is over.
