Thunderbird shows graphic error after update to jaunty using radeon driver

[hseffler]

Binary package hint: thunderbird

After updating to jaunty I am noticing drawing error in thunderbird. During the update my graphics driver was changed from fglrx to radeon, so most likely this is the cause. But I am only seeing those errors in thunderbird.

See screenshot. Marked in read ;-).

Same here.
I have got the same problem after upgrading from Ubuntu 8.10 to 9.04.

Same for me in Thunderbird after switching to the radeon driver. But I get similar glitches on some widgets in Java applications as well, see attached screenshot.

No fix for this? I wonder if this bug belongs to the radeon or xorg package, not thunderbird. Does anyone know if this is reported anywhere else? The artifacts are annoying and it is no longer possible for me to use the fglrx in 9.04.

Changed to X package, I have not seen a complaint about this bug in a while so the other bug might have been closed for one reason or another.

[hseffler (hseffler)]

Hmm, well. I am definitly still seeing this bug even with all updates applied. And yes, it is rather annoying.

I already played around with the various options of the radeon driver without success. Does anyone have an idea about what to do here?

Seems to be rather specific to only some chipsets otherwise it would have been reported much more often.

Its also not limited to thunderbird (as I noticed by now). Am also seeing drawing errors in e.g. firefox or skype. Not every application is affected though ...

[Nedenom (nedenom)]

I have not seen this in Firefox myself, are they the same kind? It seems only certain GUI widgets are affected; in thunderbird only on the bullet points, in java apps only checkboxes and the "fold/unfold" arrows.

Anyway, my graphics card is an ATI Mobility Radeon X1400.

Thanks to Alex Deucher on the xorg mailing lists I found the corresponding xorg bug and a workaround:

Bug 18397: http://bugs.freedesktop.org/show_bug.cgi?id=18397

Adding this to my xorg.conf under the "Device" section fixed it for me:

Option "EXANoDownloadFromScreen" "true"

[Nedenom (nedenom)]

I should add that I'm experiencing a major performance impact with EXANoDownloadFromScreen, so it might not be worth it.

Looks like there is another Ubuntu bug report linked to the same xorg issue, Bug #291053, maybe this should be marked as a duplicate of that.

Hi hseffler,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log or Xorg.0.log.old file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Same here, but the graphical glitches aren't limited to any specific application. I attached a screenshot of firefox showing glitches (see the GMail favicon). I'm using a Mobility Radeon X1400.

[Bryce Harrington (bryce)]

Since this is the same hardware and symptom as bug #291053, I'm going to assume this to be a dupe of that one.
