Sorry this report has been lying around.

Not sure I understand correctly, what is the error I should be seeing in this .blend?

Do you mean the dashed line that is one pixel off? (that is all around the pic though on my side)
Is that what you mean?

test_vse.blend

if you open the file, you can see there's a 1px off on the left side of the inserted image

test_vse_img_1.png it's just a 1080x900 blank img generated in blender

We now have #90785 (VSE placement of some elements is off by 1 px) which I can reproduce, will merge these reports.

This is actually different issue. I can reproduce, not quite sure what root cause is though, but looks like bad setup for v2d rect or something like that. It is mildly annoying especially when I want to see edges of image precisely.
