This happen to me while using Kodi to watch a video in fullscreen. I pressed the backslash key to leave full screen and gnome shell froze shortly after. I switched to a vt with ctrl-alt-f2, and the garbled image stayed on the screen, but I could tell that it switched because my surround system lost the audio connection then restored it after I blindly logged in. I then typed `pkill -9 kodi`. That didn't help so I typed `gnome-shell --replace`. That still didn't help so I did a hard reboot and abrt found this bug after it started. My GPU is: 02:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) I was using nouveau's vdpau video acceleration with firmware extracted from the nvidia driver according to: http://nouveau.freedesktop.org/wiki/VideoAcceleration/
Created attachment 978690 [details] Journal from last boot - contains various nouveau related errors I have attached last-boot.log, which is the output of the systemd journal from before I had to hard reboot. I has lots of error output from the nouveau driver.
I just tried the same steps with Kodi a second time (fullscreen to not while playing video) and was able to reproduce the bug.
After another reboot, I tried the same steps in Kodi with vdpau disabled and had no issues. I also tried mplayer with vdpau enabled playing the same file, and it has no issues going to and from full screen.
Tried again today with a radeon card and had no issues: 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]
@Matthias Clasen: This bug is not related to nouveau since I ran into the same bug on an Intel iGPU.
