Can someone just tell me if color management just makes performance drop or is
this really not meant to happen? Is this even a bug, or does color management
just require more powerful hardware?

This is on Plasma 6.2 beta on Arch Linux. I'll list some of the things I've
noticed with an icc profile set.
1. on an empty desktop if I move a window around, the movement is super laggy.
2. Overview is smooth.

It's very odd how performance is random; some things perform better while some
other things get worse; hopefully these all get ironed out.

I realized that the reason why the game fps seem to drops to 50 or lower is
that it's trying to match the compositor framerate when it's on.
The composer itself runs on the laptop's intel integrated gpu,

It might have been like that for awhile, and I'm just noticing it, but Direct
Scanout ceases to function in fullscreen applications when you set either the
built-in icc profile or the custom icc profile.
