None of these solutions have worked for me. Del cache, Replace Clip, Unlink and relink, nada...
In the media poll I see the update in that preview window, but the "Media in" and "Media Out" on a fusion composition doesn't update. Cache del, didn't work.
Scripts a user posted, didn't work either.
Restart works. But trying to see if a render works in a composition is frustrating. A simple light tweak for a single file and I have to restart resolve

Just want to be able to right click and tell it to refresh.
