Edge Artifacts present on speed 2 but not on speed 3

<Guest67> soichiro: I just noticed that I get strange artifacts with speed 2 that don't appear with speed 3 (red flickering line on the right edge of blue frames). I'm using the lastest git.
<soichiro> Blue frames specifically? That seems very odd. Would you mind filing an issue on the Github repo, preferably with a test clip if you can
<Guest67> I don't think it's specific to blue frames
<Guest67> But my uncommonly sized video (1788x1080) has blue frames with artifacts

<Guest67> Here's a test clip (artifacts start at frame 17)

Clickable test clip

I wonder if Guest67 could come around and upload a link to the source they used for this clip. I tried it with my own source for the same scene, but wasn't able to replicate it with speeds 1-4.

Test clip is no longer available on Disroot server

Error: the file existed but was deleted.

I recall the source was the title screens from A Clockwork Orange. Although as mentioned, I was only able to reproduce it with the version the original reporter posted, I was not able to reproduce it when using my own copy of the bluray. Sadly it does look like all the disroot links are dead and I no longer seem to have a copy.
