Description: I noticed that in both vlc and mpv (or gnome mpv) you cannot play a video for more than two or three minutes before it freezes. Sound goes on, but not the display. Freezes started right after last xf86-video-nouveau update.

I verified it was not a mpv or vlc bug by building nvidia 340.101 driver on my archlinux with testing enabled.

Additional info:
xf86-video-nouveau 1.0.13-2
mpv 1:0.22.0-2

Steps to reproduce: Use archlinux and testing with nouveau for your nvidia card or chipset. Launch a video and wait until picture freeze and sound is going on. I have to kill mpv using xkill
This task depends upon

It might be related to this issue:

Can you try and help reproduce this? No one has confirmed it so far.

Yes, mpv also exhibits the crash for me, since it uses OpenGL for rendering.

I did not get any crash, just a freeze.

I looked at which dri is used :

[fred@fredo-arch ~]$ cat /var/log/Xorg.0.log | grep DRI
[ 15.774] (==) NOUVEAU(0): Allowed maximum DRI level 2.
[ 15.903] (II) NOUVEAU(0): [DRI2] Setup complete
[ 15.903] (II) NOUVEAU(0): [DRI2] DRI driver: nouveau
[ 15.903] (II) NOUVEAU(0): [DRI2] VDPAU driver: nouveau
[ 16.987] (II) GLX: Initialized DRI2 GL provider for screen 0

glxgears hanged after a minute or so.

Looks like debian bug is nailing the problem. By the way, even with last xorg-server, opengl rendering is hanging... :(

Deactivating compositing - I had to "downgrade" to nouveau, nvidia-340xx is not working with linux 4.9 -> - and I will report if it still freeze or not.

Deactivating window compositing in Mate Desktop doesn't change anything :(

Last xorg-server in testing - 1.19.0-4 - still doesn't fix this bug :(

Had to install again legacy nvidia driver.

No issues with mpv, vlc, or glxgears on GK107 [GeForce GTX 650].

$ pacman -Qi xorg-server
Name : xorg-server
Version : 1.19.1-1

$ glxinfo |grep -i opengl
OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVE7
OpenGL core profile version string: 4.3 (Core Profile) Mesa 13.0.3

Can you please test again with 1.19.1. If you still have issues can you file a bug report upstream?

Indeed, xorg-server 1.19.1 is not showing this bug anymore. Maybe some commits added fixes this annoying bug? Can bug be closed, now?

Thanks for the info, Luke.
