Comment 1 Thomas Lübking 2013-03-08 22:49:14 UTC

Crashes in the driver, some window seems animated.

a) do you use a screenlocker/saver (that could have kicked in while you were absent)?
b) "kcmshell4 kwincompositing", 3rd tab, is "suspend compositing for fullscreen windows" checked?

Sorry, forgot to add that.
Using the "Desktop Widgets" locker (unchanged default configuration).

Yes, it's checked.

please uncheck it, this is likely another variant of bug #252817

Comment 5 D. Hugh Redelmeier 2013-03-29 18:14:15 UTC

I suspect this is not a variant of bug #252817 since that seems to be an intel driver bug and this one is in radeon code (r600g).

I would look instead at https://bugs.kde.org/show_bug.cgi?id=315089 which in turn points to https://bugs.freedesktop.org/show_bug.cgi?id=61182

Comment 6 Thomas Lübking 2013-03-29 18:36:33 UTC

Yes, is
The crash was not that "common" then and the situation sounded pretty much like "unredirected screensaver" - bug #252817 is not necessarily intel restricted. All MESA drivers seem to have trouble on unredirection and/or multiple GL contexts.
Unfortunately.
