While playing Heroes of Might and Magic 5 (Tribes of the East) under wine I noticed that at certain point in time I started getting screen corruptions (see attached screenshot) and flickering. I did bisect and it turned out to be the following commit which caused it:

    DRI2: Use radeon_get_pixmap_handle

    Now we can share pixmaps with no struct radeon_bo via DRI2.

    Fixes VDPAU video playback freezing when using an OpenGL compositor with
    DRI3 enabled.

Interestingly reverting this commit fixed DRI2, but not DRI3 (display is still corrupted and flickery).
I am using Gentoo with xf86-video-ati git, xorg-server-1.17.2-r2, kernel 4.2.3, and XFCE + Compiz (switching off compiz makes no difference).

Please attach the Xorg log file, preferably captured after the problem occurred.

For testing with DRI2, do you disable Option "DRI3" in xorg.conf or just set LIBGL_DRI3_DISABLE=1 for the app?

Comment 3 Marcin Deranek 2015-10-20 19:20:59 UTC

AFAICS DRI2 is default. For DRI3 I add
Option "DRI" "3"
to xorg-server configuration file (/etc/X11/xorg.conf.d/20-radeon.conf in my case). Effectively to test DRI2 and DRI3 I do need to restart X server.

Comment 4 Marcin Deranek 2016-06-05 09:32:23 UTC

Closing as this does not seem to be a case anymore with:
kernel-4.6.0
mesa-11.2.2
wine-1.9.11
xf86-video-ati-7.7.0
