EXA rendering worked yery well (no screen corruption) till commit "R3xx+: EXA/textured video fixes" (d79040906cd25bd494feb5901f465bbd050aa923).
I played around somethings to find out what is going wrong and fond out that the number of active pipes are calculated wrong

In my case one pipe was masked and one is marked as bad => 2 pipes

But this does not fix the issue. If I set EXANoComposite = 1 the screen looks fine but is very slow.
