Crosshatch pattern on strong colors on NTSC VHS #804

There is a cross-hatch pattern to varying degrees on the output from NTSC VHS samples which I don't think should be there: https://cdn.discordapp.com/attachments/665834485975351307/1028444042339569754/unknown.png

Unlike the "checkerboard"/blocky patterning seen especially on PAL, this is something that has not been spotted on conventional captures.

Not sure to what extent it has to do with capture setup, there seem to be some difference between vcrs and setups. Maybe tweaking the filters a bit could help filter it out.
