[BUG] Slight distortion of UI elements #2111

Closed samlay closed 1 year ago

GZDoom version

4.10

Which game are you running with GZDoom?

Doom 2 and Heretic

What Operating System are you using?

Windows 11 Home

A clear and concise description of what the bug is.

Let me know if I've just missed something in my config (here) but there's a couple of things I can't get looking quite right.

I run the game 320x200 windowed and then integer scale using Magpie or Marat Tanalin's integer scaler. I'm not trying to emulate tall DOS pixels or anything - just want simple 1:1 unscaled.

This affects Heretic more than Doom, specifically the ammo image for the equipped weapon and selected inventory item (interestingly on the inventory selection bar these render perfectly).

Here's the bad ammo on weapons 4 and 6:

Here's the flask and tome rendering correctly in the item selection bar - this is how they should look:

And how they actually look when selected:

In Doom it's just the end-of-level screen - most text here renders flawlessly but the map name is distorted:

Only reason I'm posting this is that GZDoom gets SO close now to pixel-perfect faithfulness to the original it would be great to see it get the final 1% of the way (it's the only reason I still choose Zandronum).

I should also mention I've not tested Hexen or Strife but they are likely affected too.

I can confirm this bug is present, I will see what needs to be done to fix it but I can't make any promises.

I'mk not going to bother with this. We really need full separation of 2D and 3D parts in the engine so that the 2D scaling artifacts can be kept to an absolute minimum.
