Bug 257264 – >=xorg-server-1.5.3-r1 +EXA on xf86-video-ati leads to display corruption in wine's regedit

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Rafał Mużyło 2009-02-01 18:35:29 UTC]

I'm not quite sure when I started to have this problem first.
As mentioned in the upstream bug, while I reported it against
1.1.13, it has probably happened much earlier.

Read upstream bug first.

The details, that would be nearly meaningless for the upstream bug:
x11-drivers/xf86-video-ati-6.10.0
x11-base/xorg-server-1.5.3-r1 (that should mean - the version,
with the glyph cache bug fixed)

With all the cherry-picking in xorg-server, if the problem lies there,
it may as well be that the bug is reproducible only on Gentoo.

Have you tried with slightly older versions of xorg-server, such as 1.5.2? Or you can just try to comment out the line that adds all the patches from the patchball...

Thanks

OK, now that I finally posted this bug here,
I've done some real testing.

It's all about EXA.

With XAA, I can't reproduce the bug.
On the other hand, AccelDFS driver option doesn't make a difference.

[Comment 3 Rafał Mużyło 2009-02-01 19:37:52 UTC]

OK, tested 1.5.3-r1 without UPSTREAMED_PATCHES.

Can't reproduce the problem there.

Oh, I just noticed you were using the ati driver. Could you please try using the "x11" overlay (you can easily add it using layman) and emerge the -9999 ebuild of the ati driver.

There's a good chance this bug has already been fixed, if I'm not mistaken.

Thanks

Well, seems that today's git does fix that.

On probably unrelated note:
while I was testing this, my system sort of hanged.

xserver with old driver was running on display 0,
I built and installed git driver,
gone to a different tty, started xsever on display 1,
it ran fine and the error was gone, but when I was quiting that
new xserver, I lost video (screen turned off) and input
(it stopped reacting to the keyboard).


When I restarted the system, I works as expected now - didn't
have problems with leaving yet.

I wonder if it's reproducible, but not really willing to test it.

[Comment 6 Rafał Mużyło 2009-02-03 19:26:55 UTC]

Oops, I spoke too soon.

I forgot to switch back to EXA after last tests.
It's still broken, regardless of the driver
(and it hanged on me again, damn it - it's random, again).

[Comment 7 Rémi Cardona (RETIRED) 2009-02-03 22:31:42 UTC]

I tested with wine-1.1.14 and I can't reproduce (I'm using the Intel driver though).

I still think the bug is related to the ati driver. Please file a bug over on FreeDesktop's bugzilla (http://bugs.freedesktop.org/) and please add "[e-mail]" as a CC on that bug.

Thanks
