This was not a regression on Dolphin's side, but instead it's a bug in AMD's driver for any applications which use the fullscreen exclusive extension.

strange though because anything before that worked fine. even did a fresh temporary dolphin install to be sure it wasnt some setting i was using but nope 5.0-14002 just ran really slow on VK by default. until now
