Since the update to latest XFCE version I have very weird graphical glitches on my display (does also happen on second monitor when plugged in to HDMI port). These glitches do appear only when the laptop is not idling, i.e. me moving the mouse or typing. When keeping the laptop idle for a few seconds they vanish suddenly (they do not appear on screenshots). Everything worked fine previously. I'm using an AMD Ryzen 5 2500U CPU with integrated graphics Vega 8 which might play a role for this issue.
What I've tried so far:
- Downgraded the packages: linux52 (to 5.2.4) and all mesa related packages (to 19.1.3)
- Booted via LiveISO everything was fine -> no hardware problem
So I guess it must be XFCE related, is there some easy way to downgrade all XFCE packages at once? Does anyone else experience similar glitches?
