anyway, tested it again. It doesnt hammer my igpu as strongly as it did, but, the player is very... laggy/takes time to react to user input, there's a black bar that appears when the youtube video ui is on (appears on both fullscreen and non fullscreen video) and also, when the youtube video ui is on the video will often seem to repeat past frames showing a jittery/back-and-forth motion. Pretty weird. Idk if i have the energy to report this atm
