Then add big red label in KCM: "This could cause crashes. Don't file bugs,
you've been warned". Compositing could also cause problems with buggy drivers.

For me it NEVER crashed KWin or anything.

Yes, but KWin is always running on Intel, and doesn't even know about Radeon.

No, for me it paints black screen when compositing is enabled (without
unredirection).

I can't find an option to automatically suspend compositing in KCM.
Instead there's now non-working (silently!) option for unredirection.

And... Mutter and Compiz now do unredirection by default. And seems that they
don't crash too much.
