White screen problem

[Iceman]

For some people that play my game their screen goes white when they use a really large screen size. This is because they don't have enough texture memory I assume. I set up the game with a normal window and pixel format and stuff in Cocoa. Then I create a borderless window for fullscreen thus I don't have to load in a new pixel format. Is there a way to test if the screen goes white without loading in a new pixel format?

Are you asking for a way to do error checking to test if your texture memory is full?

There is a maximum size for an OpenGL context which is card-dependent. I'd guess you're hitting that limit...

Are you capturing the display?

Are you capturing the display?
Yes. Would you like me to post some code? Can I check to see if the context is full?

[update]
I just tried it with the nehe code and I get this error "invalid memory allocation"

the full-screen code in the Cocoa ports of NeHe is rubbish. Avoid it at all costs.

Well I know in GLUT it won't switch to the 1024x768 screen size (it runs at 800x600 instead) because of the context thing I guess. I know in Oni it also wouldn't allow you to switch to the 1024x768 screen size. Is there something these people are using that I'm overlooking?

how do we know what you're missing, when we don't know what you're doing :p
