I have the EXACT same problem, and nothing that the well-meaning folks have told you helped me in any way. I finally ditched the 3-way color corrector and just slipped on the regular color corrector filter and boosted the mid-tones and a little of the blacks and that looked pretty good, and no flicker.

I had the same problem yesterday. The only way I could add an effect to a clip in the timeline was to click on the clip and then go to the drop down effects menu (as opposed to finding the effect in the effects pane/bin and dragging it over). But today, the problem has fixed itself.

Now I have a new mystery problem: I can’t click on a transition! I put 2 clips together in the timeline & normally I can click at the point where they touch and then choose a transition, like cross-dissolve. But today, even after re-starting FCP, nothing happens when I try to click at the transition point. I’ve been using Final Cut Pro for over a decade and this has never happened before.
