Issue with rotated video: flickering white and black line

When I rotate a video 180 degrees, the rotated video will always have a flickering black and white line in the top 2 pixels (running across the top of the video from left to right). This is visible in exported files, as well as the Shotcut video preview, with any video file I use. If I crop those top 2 pixels in Shotcut, the flickering line just appears again at the top of the cropped video.

Has anyone had this problem, know how to resolve?

I’ve encountered almost the same issue, and have documented my experience and solution as a bug report.

I’ve not come across this personally, but the size and position filter can be use to fix this.
