Bug 379687

Application: kwin_x11 (5.9.4)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-20-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
This may be related to my other bug reports, but I upgraded the Nvidia driver to the latest non beta and it still crashes even when OpenGL semas to be fixed. Maybe it is still broke?

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
