xorg-edgers regression: some buttons not showing in blender

[Wolfgang Kufner]

Binary package hint: libgl1-mesa-dri

Upgrading current karmic to the newest xorg-edgers packages this morning brought in among others:
libgl1-mesa-dri_7.6.0+git20090902.dc9de806-0ubuntu0tormod.
The upgrade of this package resulted in visual problems with some buttons not showing up in blender until mouse over and some buttons disappearing on mouse over as the attached video shows.

Forcing libgl1-mesa-dri down to the current karmic (7.6.0~git20090817.7c422387-0ubuntu3) worked and made all those visual problems go away.

Further investigation showed that it is the update of libgl1-mesa-dri from 7.6.0+git20090901.a8cbb156-0ubuntu0tormod to 7.6.0+git20090902.dc9de806-0ubuntu0tormod that introduces this bug. this is btw. the same update that fixed bug #423047 "xorg-edgers regression: screen corruption in blender".

I have discovered another visual phenomenon that coincides with the non-showing buttons. In blenders outliner window some icons are offset by one. See http://launchpadlibrarian.net/31478830/outliner_correct.ogv for the correct behaviour (as happens with libgl1-mesa-dri forced down to current karmic) and http://launchpadlibrarian.net/31478848/outliner_offsetbug.ogv for what happens with current xorg-edgers libgl1-mesa-dri.

A new update of xorg-edgers installed 7.7.0~git20090909.4d85a6b3-0ubuntu0tormod. This did not change the bugs status.

Please let me know what else I can do to make ubuntu karmic on intel graphics a good platform for blender :-)

Some buttons not showing up in blender until mouse over and some buttons disappearing on mouse over as the attached video blenderSep3.ogv shows.
This regression happened between commits a8cbb156 and dc9de806 mesa master. That is from one xorg-edgers daily checkout (20090901) to the next (20090902) and the best I can do to pinpoint it.

I have discovered another visual phenomenon that seems to coincide with the non-showing buttons. In blenders outliner window some icons are offset by one. See http://launchpadlibrarian.net/31478830/outliner_correct.ogv for the correct behaviour and http://launchpadlibrarian.net/31478848/outliner_offsetbug.ogv for the wrong behaviour. I can however not pinpoint when this other phenomenon showed up with the same precision. They might not be the same bug.

I filed this bug first on launchpad:
https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/423624
There is a lot of logs attached there. I do not know if any of those might be useful.

Oh. No big video attachments possible here.

Can you try the latest mesa? bug#23706 indicates blender works with the latest code.

[Wolfgang Kufner (wolfgangkufner)]

Blender has indeed come a long way. Just not all the way yet. :-)

I have also seen bug#23706 in the past, although only on the external monitor, not on the internal. I can confirm that that bug has been fixed recently.

This bug here is a different bug.
I usually run the latest ubuntu karmic with xorg-edgers ppa, which checks out mesa master daily.
Just now I checked with:
mesa (7.7.0~git20090914.d3f5a2e5-0ubuntu0tormod) karmic; urgency=low
  * Checkout from git 20090914 (master branch) up to commit
    d3f5a2e5ab413ec0dab1efa8135705e5312d361d
the bug is still there.

[Wolfgang Kufner (wolfgangkufner)]

What a nice morning. Thanks. The bug is fixed.
Works with xorg-edgers mesa checkout from git 20090923 (master branch) up to commit 20e77382935b24e9e2be89cd2b686fa2f1f67635.

[Tormod Volden (tormodvolden)]

Is this a problem in stock karmic?

[Wolfgang Kufner (wolfgangkufner)]

No, karmic is free of this bug as just confirmed with ubuntu daily-live 2009-10-13.
