kwin (4.8.4 (4.8.4)) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.1

Sama as above: went into screensaver and when I entered my password to enter my desktop again, this crash report was waiting for me there!

Comment 3 Thomas Lübking 2012-07-31 06:23:32 UTC

This bug is a duplicate of another bug and it is a bug in the driver.
There's point in reporting more crashes.

See the duplicate for possible workarounds.

kwin (4.9.00) on KDE Platform 4.9.00 using Qt 4.8.2

- What I was doing when the application crashed: the same crash again. the situation is worsed when using distro's intel drivers. solved when used xorg-edgers ppa drivers. happens sometimes, like this one, whith this driver.
