When I render my timeline for the first time, everything will look fine. Then, if I move clips around or adjust anything (lumetri, motion, etc.), it will always leave a frame of the old clip that was there or the way the frame used to look. It doesn't appear on my timeline, it's just a glitch that I can't get rid of. Something with the render leaves behind old frames that shouldn't be there. This happened before I updated it as well, and it's still not a fixed issue.
The only fix is deleting all of the rendered frames and then re-rendering, but this shouldn't be happeing.
