However, this is the first time when Kwin crashes after several reproduces of the bug. The bug was orginally reported on the NVIDIA forums due to its occurence after upgrading the driver from 378.13-4 to 378.13-5 on Arch Linux: https://devtalk.nvidia.com/default/topic/1002810/linux/gtx-1070-378-13-arch-linux-kde-plasma-5-screen-artifacts-after-resuming-from-sleep/?_sec=1&_sem=WW91IGhhdmUgYmVlbiBsb2dnZWQgb3V0IGZvciBzZWN1cml0eSBwdXJwb3NlcyBkdWUgdG8gYW4gYWNjb3VudCBpbmNvbnNpc3RlbmN5LiAgUGxlYXNlIGxvZyBiYWNrIGluIHRvIGNvbnRpbnVlIGFzIG5vcm1hbC4= The crash does not seem to be reproducible. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
