This contradicts comment #5, so it's probably not the same issue. Please file
your own report with all the necessary information.

I have same problem with card AMD Radeon HD 7730. When glamor is enabled I see
same screen corruption (as in attached screenshot) in Xserver (also in login
screen KDM). When glamor is disabled everything is OK, but very very slow.
Problem is still present in mesa, drm, xorg ati - all from git from end of
December. Problem is also in Fedora live CD which has enabled radeonsi and
glamor by default. Enabling/Disabling ColorTiling and ColorTiling2D did not
help I still saw same problem.

e4cd0f43 is a commit which enables tiling on SI by default and it's not a real
regression. I didn't tried ColorTiling2D until today, so I'm not sure if it
worked in the past (btw, same corruption with xf86-video-ati-7.2.0 and
ColorTiling2D enabled).

What was the last working version of Mesa?  Are you able to bisect?

Upgraded to libdrm 2.4.47 and the issue is still reproduced.

The issue is not observed with Option "ColorTiling2D" "off", however it reduces
the driver performance i.e. for game Openarena the FPS is reduced by approx 30%
with Color Tiling disabled.

--- Comment #4 from Michel D?nzer  ---
If the new libdrm doesn't help, does

 Option "ColorTiling2D" "off"

or

 Option "ColorTiling" "off"

work around the problem?
