I'm having a really annoying and time consuming bug with FCPX. Whenever I apply the "Keyer" effect on a clip and hit render, FCPX tries to render it without using any CPU power which causes ridiculous rendering time. However, when any other effects, and even any third partys are applied FPCX uses CPU during the rendering process -I can see this in the Activity Monitor panel.
I tried to uninstall all the FCPX applications and deleted all preferences etc. Nothing fixed the issue.
Has anybody out there experienced this bug and has a solution?
