[Bug] Incorrect texture bindings in Main Menu

[Rinnegatamante]

I'm working on a PSVITA port of the engine and I'm experiencing incorrect texture bindings in main menu only. Any idea what could be the cause? I doublechecked that the OpenGL implementation is fine by debugging strictly all the texture uploads that the game performs and everything should work fine.

Some references on the system:

• Multitexturing is enabled as well as texenv_add and texenv_combine extensions.
• Npot Textures extension is not present.
• GLSL shaders are disabled. (For now, those can be added later)
• The machine mounts an ARM CPU (32 Bit)

By doing further tests, it looks like Quakespasm is binding textures supposed to be for a specific draw actually on next draw. To make it more clear: Let's suppose Quake draws in sequence: conchars, conback, scrap0 and iterates between those, in my current state, when in main menu (during game the bindings are correct), i'll have: conchars draw using scrap0 texture, conback draw using conchars texture, scrap0 draw using conback texture.
