I'm having an odd trouble with software rendering (PrBoom Plus 2.5.1.3 and Zdoom r3875) in which textures look misaligned, even though in their hardware accelerated counterparts (GlBoom and GZdoom r1452) they look just fine!

What did I do wrong?

Which texture set are you using? At first glance it looks like a non-power of 2 texture tiling issue.

I'm pretty sure those textures came from cc4-tex.wad

Are you using an old version of ZDBSP, perchance? It used to have a bug that'd screw up alignments in ports that don't disregard the alignment data on segs.

I'm using the one that came with Doom Builder 2 (2.1.2.1553) Should I change it?

EDIT: I should mention that since I got Doom Builder 2 I've never changed the default nodebuilder configuration, so it's ZenNode for boom maps

But it's a problem that had been fixed in PrBoom long ago; and that has been fixed in ZDoom more recently -- it definitely wouldn't happen in ZDoom r3875.

Even if it were the case, that wouldn't have affected ZDoom.

Are you sure? I've seen it in Prboom-plus 2.5.1.4 (software mode) like two months ago.

So is there a way to fix this? Or should I use a hardware accelerated port?

If your textures are 56x56, don't tile them - or re-composite the textures so they have power of 2 dimensions (64x64 or 64x128).

Try this test map I threw together, the problem's still very much in evidence in PrBoom_plus 2.5.1.3 and ZDoom r3794 though I had to deliberately use oddball texture sizes.

Yeah I changed the textures for ones with standard Doom dimensions and now it looks just fine.

I'm curious though, why do that bug occurs?

Just a heads up. The issue has been fixed from ZDoom's side.
