-- Information about the crash:
Dolphin crashes on monitor turn on when DP is being used. The machine is working. I just turn off my monitor, go to lunch or something, when I return and turn on the monitor, Dolphin sometimes crashes immediately. It never happens if I'm using HDMI.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
