--- Comment #62 from Topi Pohjolainen <topi.pohjolainen at intel.com> ---
I got curious if the failing case is for some reason getting pixel values for
the previous framebuffer. Note that even the simplest case requires two
internal rounds (the test wants to try with different sub-regions - in my case
these are now identical as the region is hardcoded).
I modified the test to use different pixel values for the first and for the
second round. The second round fails and the failing pixel values are such that
would be valid only in the second round (in position 0,8 the values are such
that would be correct for position 0,0). The pixel values are such that
wouldn't be valid for any position in the first round.
