Description Luke-Jr 2014-12-23 03:48:58 UTC

When I fullscreen a video in mplayer2 (gl3 vo driver), my display freezes - usually for a number of seconds - after which the fullscreen completes successfully and continues playing.

Sometimes the hang is very brief or even unnoticable (I think if I had recently played a video fullscreen - which may make troubleshooting harder).

During the hang, CPU appears to be idle, I *think* I/O wait is high (but nothing showed in iotop), and perf top didn't notice anything busy.

This does not affect my 5850 card, only the 7950.

Please attach your xorg log and dmesg after the freeze happens.  Also, what kernel are you using?

Comment 4 Luke-Jr 2014-12-23 21:13:24 UTC

Note, I don't see anything related to the freeze in either log.

Comment 5 Michel Dänzer 2014-12-24 08:10:13 UTC

I can't seem to reproduce this.

Does it still happen with glamor from xserver 1.16 or later?

What window/compositing manager are you using?

I have glamor 0.6.0 - is that current? (Gentoo doesn't have anything newer, it seems)

> What window/compositing manager are you using?

KWin with compositing disabled.

That's the old standalone glamor tree. Please try glamor from xserver 1.16 or newer.

Do I need to restart X to try this? xorg-server 1.16 is not considered stable, and I encountered actual problems with some version post-1.15.1 (sorry, don't remember what) - so I'd rather avoid the upgrade if possible..

Yes, of course.

If you try xserver 1.16.y and the problem persists, please attach the corresponding Xorg log file.

I've not been able to reproduce this since upgrading.
