Description Jure Repinc 2011-05-12 18:55:27 UTC
After updating the mesa today KWin started to crash/segfault on start. I've bisected and the first commmit that causes the crash is:
r600g: delay mapping until first map request. (v2)

This is with KDE KWin 4.6.3 and on a laptop with integrated ATI Mobility Radeon HD 5470.

Later I've also tried with glxgears, which appears to work fine if in window and crashes if started with -fullscreen option.

Same commit cause problem there.

Using EVE-Online game. The game crash between "login" and "characters selection" after I have updated to the latest git drivers.
