Hello there,
I found a bug using ACTION2.WAD in Gzdoom. This bug didn't appears in Zdoom, here is a comparison :

I'm also getting that problem on my iMac. The cab looks fine in ZDoom, but in GZDoom, the texture is shifted halfway down.

Does your video card support non-power-of-two textures? (I'm not sure but that might cause these sorts of issues.)

I tested on a 32-bits system equiped with a Geforce 8800 GTX and on a 64-bits system with an I5 processor graphics. The same bug on the two different systems.

Yeah, I'm seeing the bug too on Win7 64 bit with a GeForce GTX 285.

It was broken in
r1460 but at the moment I have no idea how to fix it without reverting gl_walls.cpp to previous revision.

Fixed
I knew it that the patch would cause some problems. I didn't apply it and unfortunately I never had the time to properly check it.
What it did wrong is simple: Instead of the scaling factor coming from the map data it used the composite scaling factor of both map data and texture definition which effectively applied the texture based part twice.
This is why I am very careful with user-submitted patches that change sensitive code. This should never have been added without a full review of the effects.
