Then for that data it prepares primary plane, spanning the whole screen, also filled with the same blue color and black holes for each of the other planes, so that the holes would be covered by the overlay planes. The final result, if blended correctly, should be a solid color on the whole pipe. We compare the CRC against a CRC we gathered from solid primary plane with nothing overlayed. This test failing may mean there are inaccuracies in blending planes. User impact: small, as not much software is using multiple planes, and we have other tests that seem to be fine with 2 planes / cursor. Recommended next steps: extra logging for plane positions and maybe manual verification/Chamelium capturing the broken frames for manual inspection.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
