Description Wolfgang Kufner 2009-09-15 04:24:47 UTC

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.

Comment 3 Wolfgang Kufner 2009-09-15 23:42:48 UTC

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.

Comment 4 Wolfgang Kufner 2009-09-24 00:07:20 UTC

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