--- Comment #3 from Arek Hiler <arkadiusz.hiler at intel.com> ---
The test first grabs reference CRC from a pipe with primary plane being filled
with green.

Then, for each non-primary plane, it sets up the pipe the following way:
1. primary plane is green but with 64x64px black square at position 100x100
2. the non-primary plane is set to be 64x64xpx green square at position
100x100, basically covering the black hole
3. compare the CRC of fully-green primary to CRC of the setup with the hole
covered

This kept failing for 7th(!) plane on all our ICLs, but it was last seen 2
weeks ago.
