Multicam angles in viewer mysteriously resize.

With FCP X 10.4.4 I am having an issue where while editing the angles on the storyline, the sizes of the video frames change in thew viewer as if they're zoomed in and I can't see the entire image. The only way around this has been to relaunch FCP X. Anyone experiencing this and have a solution or perhaps it's a known bug?

I have three angles: two 17 1080p, the third and 4k on a 1080p timeline.

I used to see this frequently on past versions. Yes it was very frustrating. In my case it was 2 or 3 angles, all 4k, always using proxy. I don't remember doing anything to make it go away but I haven't seen it in about a year. Maybe others have better suggestions.

Yes, this bug has ben around for as far as i can remember... most commonly for me is if the clip has been resized... very very annoying...
