You have 2 graphics cards, you need special setting. Which GCard run at boot? Intel or ATI? Can you set it? if not probably Intel first...

seems, that picom is your last problem :D :D :D :D

Thank you for the articles! I'm doing it as described  in the unximen article; when only using the Intel card, picom seems to run fine and with the --experimental-backends flag most screentearing is gone too.  I'll use the AMD card when necessary with DRI_PRIME=1. Thanks for your help!
