Oof, never seen that before and it sound pretty bad to me. Like a kernel driver, mesa or hardware bug. Certainly shouldn't be normal with up-to-date hardware like this.

another freeze

Another freeze this time when I was watching a youtube video and it freezed. I was able to move the cursor and switch workspace etc but I was still seeing the blocked video.
It's becoming UNUSABLE. It's happening way too often. I'm trying to switch from this lts kernel to a newer one.

Anyway, I think this is an AMD bug, not a Firefox bug

a.geno, is this still happening for you?
