dmesg

My system runs fine until I try to start com.valvesoftware.Steam or org.signal.Signal via Flatpak (org.zulip.Zulip works fine). Then the graphical X screen locks up and does not react to input (key presses, mouse clicks) anymore. Moving the mouse cursor is visible. I can move to another VT (ctrl+alt+F2), log in and flatpak kill ... the offending application, switch back to the first VT and the system is back to normal without any obvious damage. In dmesg I will find a bunch of messages like these:
[ 204.449968] amdgpu 0000:0a:00.0: [gfxhub] retry page fault (src_id:0 ring:0 vmid:1 pasid:32770, for process X pid 2148 thread X:cs0 pid 2151)

Device 0000:0a:00.0 is an AMD Ryzen 5 2400G.
