From 8954d99659e3b793c99441e1fa8b6d474cbf343b Mon Sep 17 00:00:00 2001 From: Rui Matos <tiagomatos@gmail.com> Date: Mon, 6 Jun 2016 20:28:34 +0200 Subject: [PATCH] shell-recorder: Avoid a crash when the cursor texture is NULL When running as a wayland compositor, MetaCursorTracker might legitimately not have a displayed cursor because e.g. a client unsets the cursor surface. Note that, under an X session, the assumption that the tracker always has a cursor texture is true because XFixesGetCursorImage() always returns data even if the cursor isn't visible. https://bugzilla.gnome.org/show_bug.cgi?id=767001 --- src/shell-recorder.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/src/shell-recorder.c b/src/shell-recorder.c index ef729ff5f..e7562ef01 100644 --- a/src/shell-recorder.c +++ b/src/shell-recorder.c @@ -321,6 +321,9 @@ recorder_fetch_cursor_image (ShellRecorder *recorder) guint8 *data; texture = meta_cursor_tracker_get_sprite (recorder->cursor_tracker); + if (!texture) + return; + width = cogl_texture_get_width (texture); height = cogl_texture_get_height (texture); stride = 4 * width;
