I'm having a problem with a mod I have created. In a nutshell, when users toggle between windowed and non-windowed video modes, nearly all of the textures for my various graphic elements disappear. The frames are all still there and things like text labels and such still appear, but all custom textures vanish.
Toggling windowed modes again, switching video size and other similar actions do not fix the problem. The only "fix" is "/console reloadui"
Can anyone tell me what the root cause of this type of behavior might be or how to solve it?
