Is this about seeing if I no longer need the i915.force_probe=46aa option, or
about the tearing problem?

Anyway, I'm willing to try the sle15-sp5 kernel (I'll be running it in a few
months anyway), but I don't know how. If some writeup is available for that
somewhere, I'd appreciate a pointer.

I haven't seen the problem manifest anymore, but I don't know whether it's gone
or not, maybe it's about coming back from sleep, maybe it's about a graphics
process being started on or migrating to an efficiency-core, maybe it's about
unhooking and rehooking to the dock. No clue.  So I'll give it a few days to
see if it reappears.
