Screenshot

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:

commit f8b0f23e9f4af9f9097ee5e72d53b45173163c41
Author: Michel Dänzer <<a href="mailto:michel.daenzer@amd.com">michel.daenzer@amd.com</a>>

    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).</pre>
