How to configure backgrounds for maximum quality?

[matchination]

Hey guys. I've actually been a lurker for about five years now, but I've only recently ran into a question I've had to create an account to ask a question for.
The game I'm working on is not in the usual pixel art style, but actually has art with sharp, clean lines. And that's giving me some problems. The way I've set things up with AGS seems to degrade the image quality of the room backgrounds I use. An example:

(In-game. Note how the "O" gets especially deformed)

In-editor:


The image is a 1024x768 PNG. I've set AGS to render 32 bit color at that resolution, with no avail. Switching rendering from Direct3D 9 to DirectDraw 5 seems to make no difference whatsoever. What am I doing wrong?

What type of scaling do you use?

I think that's what may happen if stretching to whole screen scales the game by non-even multiplier. In that case some pixels may become "wider" or "thinner" than others. Try using "max round scaling" option to see if that fixes the issue.
