https://bugs.freedesktop.org/show_bug.cgi?id=100306 --- Comment #41 from MirceaKitsune --- I have important new information. After yet more weeks of testing, I seem to have found both of the common triggers for this issue. The crash happens a few hours after either of the following actions is preformed: 1 - Desktop effects are toggled at runtime. Pressing Alt + Shift + F12 twice to turn compositing off then back on will mine the system with this crash. 2 - I insert my USB stick or external drive into an USB port, mount it and access it in Dolphin, then unmount and remove it. A few hours after I've inserted / removed my drive, the freeze occurs. I suspect this has to do with the device notifier popping up in the system tray, asking what action to preform on the device or telling me the device is safe to unplug. I'm not sure if the themes I'm using might have any relevancy. Considering this is a graphics problem, I figured I'd share this info as well so others can test them if they wish. I'm using the Plasma / KWin theme Freeze with the default Breeze icons / cursor / widget style: https://www.opendesktop.org/p/998653/ https://www.opendesktop.org/p/1002663/ -- You are receiving this mail because: You are the assignee for the bug.
