Yes, I'll get some false positives. Theoretically. But in practice:
- What's the problem with unredirected fullscreen unmanaged window? It could cause flicker once, nothing more.
- I've never seen such windows (where I didn't want unredirection).

I get black screen when I run something with DRI_PRIME=1. And after reverting it everything is fine again.

Suspend compositing instead of unredirecting? I'm not against it, I'm against removing single-checkbox solution.

> you're asking for a single target ("you") solution
Solution for a single target (me) is git revert.
