I double-checked the workaround and it still didn't work.
The photo this time shows what LightDM looks like after I run "sudo mir_demo_client_egltriangle" on another VT. The triangle looks perfectly fine and spins with smooth 60 fps, but everything else is still garbage.
I don't have the time right now to downgrade all mir-related packages, but I'll try that later.
