Crash on KDE 4.6.3 when using Alt+Tab with "Box Selection" effect ON
 

Hello,

I have just updated to KDE 4.6.3 (Slack 13.37) using Alien's packaging.
First thing I noted while using it was that it would crash and exit when pressing Alt+Tab, specially when only one window was opened.

After some testing, I verified that with all effects OFF, it would not happen.
Then I tried setting the effects ON again, and finding some effect that might be ON by default that was related with Alt+Tab. Lo and behold, there is an effect that makes Alt+Tab produce a miniature of the opened windows.
Disabling this effect has solved the issue.
I tried finding the exact log message for that, unsuccessfully.

Not sure where to report this, but I think leaving this topic here might help someone who may have the same problem.

Edit: Updating from mesa-7.9.2-i486-1 to mesa-7.10.2-i486-1 (/testing) everything works fine

I am experiencing the same problem that Alt+Tab causes a crash. Basically any of the desktop effects like the ctrl+F8 to show all desktops causes a crash as well. When all desktop effects are turned off then Alt+Tab works as expected.

Holy shitballs ctrl+f8 made it crash here too

What fixed it for me was upgrading to the mesa version in the /testing directory.

Thank you, I just updated from mesa-7.9.2-i486-1 to mesa-7.10.2-i486-1 and everything works fine now
