I have the latest update of FCPX in a macOS High Sierra 10.13.6.
I am having a recurrent issue with a glitch that appears randomly in clips after I do color or exposure changes:
If I replace the clip the glitch disappear, but if I paste the attributes, the glitch comes back. If I do a minimum change, let's say moving one 1% the exposure or saturation, the glitch disappear. One of the problems is that sometimes I discover the glitch or glitches after I exported the project, so I have to re-do everything again. Do you know why this happens or better, how I could prevent it?
