[Bug 43406] NieR:Automata - Bloom to bright

https://bugs.winehq.org/show_bug.cgi?id=43406

--- Comment #18 from Philip Rebohle <philip.rebohle(a)tu-dortmund.de> ---
Seems like the root cause of the compute shader misbehaving is that it reads
from an image resource that is currently bound to the frame buffer for
rendering. According to [1] and [2], the values read by the compute shader are
undefined as a consequence.

In order to fix this, wine should unbind the FBO prior to calling
glDispatchCompute.
