I am getting window menu corruptions in KDE 4.12.5, as shown in the attached
image, on Gentoo with kernel 3.14.10 and the following software stack:

x11-libs/libdrm-2.4.54  USE="libkms" VIDEO_CARDS="radeon"

x11-drivers/xf86-video-ati-7.4.0  USE="glamor udev"

Only active use flags are listed.

With mesa from today's git the corruptions appear on the whole screen, like in
the attached image (see full_screen_corruptions.png).

After quick bisecting, it looks like commit "radeonsi: Use dma_copy when
possible for si_blit." (5d5c20920e0e570742a497aa047e99a2fa3c04f2) is
responsible for that. When reverted, the full screen corruptions disappear, but
window menu corruptions still persist.

See bug 80787.

The kwin menu corruption is most likely a glamor bug. You can work around it by
selecting 'Raster' for the rendering engine in the kwin advanced desktop effect
preferences.
