Mainly Black Playback Screen

I inserted an image on top of my video and tried to paste a filter. Immediately following the paste, my playback screen went mainly black for the entirety of my video.

I have exited ShotCut and restarted my computer but the problem remains. How do I return to normal colors on the playback screen?

You have a filter applied to the master track. That might be causing the problem.

Thank you very much. That was exactly my problem. I don’t know how the master filter was manipulated but non-the-less that was my problem.

I really appreciate the help.
