Combining effects Edge Crop and Position And Zoom causes target clip to have flickering thin line on bottom in both preview and export. Prepare: * white background for your project to see problem clearly * some clip smaller than your project, preferably also white Reproduce: 1) Open project 2) Add your white background to video 1 3) Add your clip to video 2 4) Add Position and Zoom to clip in video 2 5) Click Adjust to original size 6) Center the clip position 7) Add Edge Crop to clip in video 2 8) Set Right crop to 1 pixel 9) Observe artefacts on bottom of clip Artefacts are also present in export, at least for .webm
This seems similar to Bug 384967 where the size of clips and picture doesn’t match the project settings.
