First time posting but i have learned a lot from this forum.
I have an issue on my IMac 27" Retina 5k (late 2015). Running FCPX 10.4.5 however the same issue has occurred on previous versions.
Essentially the timeline produces this flickering pixel array across different clips on different projects. Never the same, happens with or without plugins, grading etc. But Never anywhere else but the viewer. When exporting, the flickers remain on the output files.
Sometimes on first boot up i can export a timeline without skimming etc and i can get a clean export. Seems to be no continuity with the issue.
To make things stranger. I run the EXACT same set up on my Macbook pro and have no issues what so ever. I literally plug the same HD in there and open the same project and no pixel flickering.
I have seen similar issues on here, that suggest changing the clips to REC709 override in the settings. This hasn't helped. Anyone run into the same issue?
