It should not be a critical bug, it should not be fatal to the GPU, just a nuisance. It is not clear whether these are erroneous faults or some corner case we are not handling correctly - unfortunately the GPU doesn't actually report the faulting address - though maybe inspecting current->comm could name the suspect driver.
