Public bug reported: I'm using KDE 4.8.5 on Precise on a box with a AMD Radeon HD 7560D graphics card. Desktop effects are enabled. When resizing windows and (more rarely) also during various other activities (such as closing a window), X crashes. This isn't completely deterministic, but if I open a handful of windows and resize them, I can reliably produce an X crash with return to the login screen in far less than a minute.
I'm not 100% sure I'm reporting the right module. I guess the question is whether the Radeon driver or libpixman, but I'm sure we'll figure that out soon... I'd be glad for any pointers, this is obviously really annoying. $ lsb_release -rd Description: Ubuntu 12.04.2 LTS Release: 12.04 $ fglrxinfo display: :4 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.
