Merge r260570 - [GTK] Crash in cairo_surface_mark_dirty_rectangle() in accelerated compositing mode under X11
https://bugs.webkit.org/show_bug.cgi?id=210636
Patch by John Frankish <[email protected]> on 2020-04-23
Reviewed by Carlos Garcia Campos.
When cairo is configured to use xcb instead of xlib, it might use an image surface attached to the xlib one as
snapshot. In that case a flush is needed to detach that snapshot after we have drawn the surface in the
context.
* UIProcess/gtk/AcceleratedBackingStoreX11.cpp:
(WebKit::AcceleratedBackingStoreX11::paint): Call cairo_surface_flush() after drawing.
