Comment 3 K Freed 2022-07-12 00:55:02 UTC
The issue clearly has to do with the 2 gpus as disconnecting one of them fixes the issue
Comment 4 Nate Graham 2022-07-13 19:58:24 UTC
Seems like our code is getting confused about the number of screens or something?
Comment 5 David Edmundson 2024-04-25 14:31:39 UTC
If a client crashes, it's a client problem not a kwin problem
