Subject: ui/gtk: Draw guest frame at refresh cycle
X-Git-Tag: v9.0.2~25
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0d90c36d9c1eda2a7c39839475df4bf3f4758920;p=thirdparty%2Fqemu.git

ui/gtk: Draw guest frame at refresh cycle

Draw routine needs to be manually invoked in the next refresh
if there is a scanout blob from the guest. This is to prevent
a situation where there is a scheduled draw event but it won't
happen bacause the window is currently in inactive state
(minimized or tabified). If draw is not done for a long time,
gl_block timeout and/or fence timeout (on the guest) will happen
eventually.

v2: Use gd_gl_area_draw(vc) in gtk-gl-area.c
