Comment 1 Thomas Lübking 2013-04-18 11:09:56 UTC 
driver bug.
using mesa 9.1?

(random guess)
Might be induced by falsely picking a msaa FBO. in case you can, try whether picking https://projects.kde.org/projects/kde/kde-workspace/repository/revisions/a021eacfbd2f2e8cb1f1caf1b66204880c1e7992 resolves it.

what it do?  where was it pick? Sorry for bad English
Comment 3 Thomas Lübking 2013-04-18 11:34:45 UTC 
If you compile yourself, you could just add that commit as patch (or update to current 4.10 branch in git)

If you don't know how to or want compile from sources, there's nothing that you can do in this direction (except for waiting until 4.10.3 hits your distro)

-> You can also just use the nvidia blob (binary driver) instead.

Comment 5 Thomas Lübking 2013-04-18 11:59:29 UTC 
You don't need to help /us/ ;-)

The bug is in the nouveau driver (even if kwin would pick an msaa visual, and this would lead to the crashy path, the driver should not crash but be slow or sth. like that)

Also compare http://www.mail-archive.com/desktop-packages@lists.launchpad.net/msg219457.html - referencing a game called "Tibia", blaming the mesa 9.1 update.
