Ingame graphics problem

So... I don't know what seems to be the problem, but in game, there are those little irritating semi-transparent lines on the buildings roof. Probably this is linked with the priority, because if I lower the priority, the lines go away, but, well, should player step on it, it would look like player somehow got up to the top.
If I recall correctly, I didn't change anything in tileset (nor metadata, nor the graphics), this is a vanilla tileset. And it doesn't show any of those lines in the tiles selection.
What to do?

This is a known, unfixable bug when playing on the Large screensize and up.

So nobody was able to solve it by coding, right? Are there any other ways to solve this problem (like putting the screen back to smaller sizes and do some voodoo magic with dances and sacrifice), or I am stuck with this for eternity?

You can play in smaller screen sizes, sure. 0.5x and 1x work perfectly fine at least.

It?s a rounding issue with the sprite resizer, but that?s such a big mess that Maruno probably thinks it?s no worth the bother.
