This is concerning that after all this time (2,5 year) this issue is
still here.
I have the same issue shown in journalctl. I believe it wasn't there from the
start but showed a while ago. I don't see any problems on the frontend site,
however.
I have a hybrid GPUs and currently use optimus-manager to switch between GPUs.
Nouevau is making the switch (successfully).
Here is the bug:
