Problem summary Apple ProRes renders with missing scanlines on Linux
This issue seems to be intermittent but reproducible
it doesn't seem to happen with -m 1, so may be threading related
tested with both 4444 and 442 codecs and reproduced
Customer reported version nuke.14.1v4 colorway.n/a
Customer reported platform centos7
Steps to reproduce
1) Launch Nuke
2) Open the attached Nuke script
3) Render 1500 frames with the Write node
4) Read the image back and check each frame for missing scanlines*
There's an automated tool in the Nuke script to find missing scanlines
Expected behaviour For Nuke to write all the scanlines on every frame
Actual behaviour Randomly on different frame, different scanlines are missing from the render:
Workaround If you render with -m 1, the missing scanlines don't seem to appear, however renders go from 3 minutes to 50 minuets, so it's not a good workaround
