I tried last version.
When I load this problematic source and I set cropping to 704x426 it disables filtering.
When changing it to 704x428, filtering is back again.
Good!!
Some button in the GUI, as there's in the resizing part, to adjust vertical cropping to mod4?.

Just a sugestion if you find it may improve Hybrid...]
