Mmm... ok it's when I'm using a shader that the bug appears (without shaders,
it works), I'll try to run gallium in Debug mode to see if the shaders outputs
are correct, and if so, this is probably the attached framebuffer texture or
image which is bad updated. (No matter if I use an image or an FBO as render
target, the bug, the bug is still present then)

I tried to use primitive synchronization objects and memory barrier to see if
it change something but not the problem seems to be in the draw function.

I can't guarantee I'll be able to do something about this, I've no knowledge
about driver management, my game project already takes me a lot of time, and I
don't thing I'll have the time to remake a driver if I can't fix this bug so I
have two choose :

-Hoping this bug'll be fixed.
-If it's not the case, not using shaders.
