You can ignore my comment 27 and comment 29.

For some reason with the first compute shader patchset the compute shaders
would compile fine but not *really* work, at least for me - but for others they
did.

Now with v2 they work for me too - mostly. In some small areas there still
appears to be some colorful flickering. Here's how it looks now:

Where I see some colors that I think shouldn't be there: very briefly at 2:36
and 2:38, from 2:50 ongoing the door and some short flickers on the whole room,
then 3:20 the same door, and lastly from 6:20 ongoing that room. But it's no
comparison to before..
