UMR is system wide any way, it's memory/registers/HW debugging tool. you can
provide the UMR outputs I asked before once the freeze happened assuming you
still have SSH access (which seems like you don't).

Since the memory faults you experience are clearly due to some graphic
rendering activity maybe you could try to isolate the app which triggers it,
repeat what you do but close both firefox and dolphin and check if this still
happens. If not try to find which of them was causing this and then we can run
it with MESA debug flags.
