I just noticed this happens when adding subtitles too. This may be an alpha related issue?
Which type of clip do you use (MP4, 1080p25fps) for rotoscoping? If you use a video from a mobile phone with variable fps: convert the video in the project bin first.
Cannot reproduce in linux master branch.
I have tested with 21.12.0. Following your steps with rotoscope and add subtitle. Render to MP4 is working. Please test with the latest Kdenlive version.
