Further, I've tried to chuck the all code inside thread subroutine into
critical sections to force execution of all filters consecutively (like it
happens without multithreading). Alas, it also resulted in the same random
behaviour. I cannot think of any reason. Any ideas how to debug it further?
Could it be that affine transform often requests data from outside the area
of an original image? I guess there is no reason why this wouldn't be
handled though while launched from a separate thread as opposed to the
parent process ...
