Keep old 'dependent' state of unaffected planes, this way new state takes into account current state of unaffected planes.

Okay. But now I'm thinking that it's probably not really worth to backport this patch at all because it doesn't fix blending entirely, but only makes it good enough to show cursor plane properly. I'll send V2.
Ah, didn't notice that I don't have to re-send. I've spotted other problem in the patch, so will just send V2 ;)
