Please attach your dmesg output as well.

What 3D driver are you using?  r600g or r600c?  Are you using a compositor or not?

vanilla kwin with r600c.

SuperTuxKart with color tiling, r600g hd5850

mesa from current git works fine wit color tiling enabled so it seems an old bug still present in 7.10.2 for cypress/evergreen at least. Still a check for a recent enough mesa might be a good idea before enabling by default?

pulling latest mesa/libdrm/ddx again still has the corruption with color tiling on with r600c.  I tried r600g and the corruption is not seen.

That's strange, I'm using 6850 with r600g and still experience corruption, in fact I've had those errors for a long time but didn't bother to report since I assumed it's still work in progress.

I also have this problem on Debian Sid (x86_64) with self compiled ddx (6.14.99) and KDE (effects enabled). Switching back to Sid's 6.14.2 fixes the problem.

As already noted the corruptions happens a few seconds after login so probably related to KWin effects.

If I disable KWin's effects there is no more graphics corruption.

on my AMD Radeon 6850 I've got that corruption with *when I enable* colortiling too. There is no problem without.

As of 5ff22ab I no longer experience any problems with color tiling on 6850 (so far at least).

I see there are recent commits so I pulled libdrm/mesa/ddx again just now.  Same as above for me, r600c with kwin is showing corruption still, r600g is clean.

I've just pulled mesa+ddx git again. Nothing changed.

To make it clear, I am using

are you using any other drm stuff perhaps?

No, I'm using latest git versions, 64bit Gentoo, 2.6.39 (git) + some stuff from airlied repo (radeon-testing/fixes; I'm waiting for some 'stable' rc to test 3.0), Xfce4/xffw4 with composition enabled but I should note that I'm stick to r600g, I didn't tried r600c in months.

It's just a guess but perhaps your system is overwriting some files or you are using 32bit version of mesa (things like flash for example - I'm using chroot environment to create 32bit packages) ?

Just to be sure, I've just updated

I still have the "corruption" with color tiling, nothing changed.
Anything else I can paste/check?

Above might be gentoo specific but anyway I suggest you to check what's in /usr/lib[64]/dri and what `make install` (or whatever you use to install mesa) do on your system.

You were right. There was something wrong with the system.
Being uptodate now with drm/ddx/mesa gives me NO MORE corruption with colortiling.

Seems fixed for everybody with r600g. r600c problems would need to be tracked separately, but might never get fixed.

The corruption is still present with r600g from mesa 7.10.3 on evergreen. Although it is fixed in recent mesa from git.
