I have experienced this problem quite a lot on a mac. If I change the aspect ratio of the files then the problem can go away but I have not formulated a pattern yet.
What I have noticed, if it helps, is that the default transition seems to work on all files that otherwise fail with a more complex transition. Does that help?

Yeah, I know why it's happening, just haven't had the time or motivation to fix it since I'm no longer actively using this in my project (switched to ffmpeg-concat).
The reason it doesn't repro for the simple fade
transition is because the fade transition maps each input pixel directly to an output pixel.
The problem happens because ffmpeg internally adds padding to each row of memory with some video resolutions, and this implementation doesn't take this into consideration.
