Texture bug in PSX TC?

[JFAD1494]

I'm playing the PSX TC on the latest GZDoom Devbuild and I've come across a texture bug on the Nightmare Spectres. Instead of being just cyan, they're a cyan/red colour. Here's a screenshot that I took the other day

Can anyone suggest a fix for this problem?

They use subtractive translucency so their color depends on the background. But yeah it does look a bit odd here. There's even one part of the sprite that isn't translucent at all. It doesn't look like for me.

I tried a different version of GZDoom, and that seems to have fixed it. The Nightmare Spectres are completely cyan.

So, what version had the bug and which one was working?

[JFAD1494]

It was one of the Devbuilds that gave me the bug, and it was version 1.9.1 that worked.

Hm 1.9.1 is the old, obsolete one. What's your graphics hardware?

[Graf Zahl]

Looks correct to me in the current version. I have no idea what might be causing it. Can you post your hardware specs? I suspect a driver error here or something like that.

Ok, since there is no answer, this will go away now.
