I think both major HUDs will do this to PS at some point, depending on unknown machine specs
I *think* AHK-HUD is immune, but I couldn't be certain (and it only works on PT3 database aorn). Have you tried with vanilla PA-HUD+PT2 also?
edit: ^^^ F5redrawtable doesn't help IIRC, at least not when I've been developing scripts that can trigger this very annoying graphics glitch
Can't hurt to try however...
