-- Information about the crash:
After a reboot due to an update (made with Discover), Dolphin and Konsole crash when i try to start them.

As a workaround, I 
- unplugged one of my 2 external displays
- started Dolphin
- replugged my screen
- the opened app works but i cant open a new one or a new window without a new crash

Here is my hardware
