Lines on perspective crop - bug in Premiere Pro AND Media Encoder

- Steps to reproduce - (Very important!) Bring a video into a sequence and perform a perspective crop. This crop will show multiple vertical lines. The proxy/preview will show lines and the final render will also contain these lines. This also appears with the same version of Media Encoder when encoding the file. Fix: use version 24.1 or earlier but later than 24.0.3. This has also been reported in the Community Forum circa this past December. One person reported that adding additional effects before and after (Transparency and Invert) solved this, but it did not for me.
- Expected result - When reverting to version 24.0.3 of Premiere (and Media Encoder) the issue does not appear.
- Actual result - Version 24.1 still shows this bug. Perspective crop apparently uses software and not hardware encoding and since the bug appears after 24.0.3 it seems Adobe introduced this bug after 24.0.3.
