Xorg log
When SDL has a window open which is the same size as the screen and it switches
to fullscreen mode it sometimes breaks the driver and an Xorg restart is
required. After the SDL application exits the whole screen continues to have
corrupted display. It seems like old data from the window is sometimes
displayed. Or sometimes just random image corruption appears. It only happens
if the non-fullscreen SDL window is exactly 1920x1080 (the size of my screen).
I noticed this problem when watching 1080p video with ffplay (from ffmpeg), but
I have created a small program to reproduce the bug have attached it to this
report.
Program versions (all from git):
Xorg: 1.14.2.902
xf86-video-intel: 2.21.15
libdrm: 2.4.46
pixman: 0.30.2
libXdamage: 1.1.4
