When GPU processing is enabled, a red line appears at the bottom of the screen that reads: "Experimental GPU processing enabled - not for production."

I can see the logic of having this appear the first time the feature is enabled, or even on every occasion, but it should, in my opinion, at the least be dockable.

I find the bright red bar a bit of a visual distraction given that there's no way to get rid of it.
