AMD Ryzen 7 2700U w/ Vega 10 Freezing on 5.5.x Kernel
Created due to a downstream bug from LaunchPad
The full report is in the linked LaunchPad bug report, but the brief is that when doing something mildly graphically intensive—like alt-tabbing, moving through a webpage, etc—will have a chance to cause a momentary freeze before continuing. Occasionally during these freezes items that should be occluded will appear over something, like desktop icons in front of Firefox.
This was noted in journalctl -f
