Makes sense to me. Now, while repeating me being clueless about this 
code and even technology outright, I've wondered if the thing to do 
might even just be refusing to enable/use DRRS on this old Haswell-era 
hardware

Probably not a theoretically/technically sound/interesting  plan -- but 
it sure would solve things for both me/us and the Ubuntu/freedesktop.org 
bug-reporter, and frankly, I don't think anyone on a system like that in 
2025 would know or care in the first place. They just very much mind the 
flickering...

Maybe stupid; maybe regresses a ton of Haswell-era systems on which it 
does work fine. No idea...

Rene
