-- Information about the crash:
- What I was doing when the application crashed:

launching ath of exile (using primusrun)
This was immediately after a rpm updates for primus which supposedly improved performance of offloading.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
