When updating from LWJGL beta 3 to beta 4, on a certain machine my application shows just a completely white screen. I can tell from the server connection that the application is functioning, only the screen is completely white. I doublechecked by returning to beta 3 and everything is running smoothly then, so it is definitely a problem with beta 4.
So far it has occurred on only one machine.
Any ideas?

Yes, we have found quite some SIS cards that need massaging the drivers before they work. But in this case, I can switch back and forth between beta 3 (working) and beta 4 (white screen), so we didn't try to change anything about the machine so far.

I'll try and get Elias on it, since he's the only one that modified the internals between 3 and 4

Bah, stupid SIS cards. I'm not sure what went wrong in beta4, but fortunately the changes in that area (windows opengl) were limited. Can I ask you to test your application in windowed mode?

And another thing: are you using pbuffer or multisampling in the PixelFormat?

I'll check about the windowed mode.
I don't think I am using any of that - at least I don't know what it is :-)

Are you using gamma, then? And can I see your initialization code that creates the Display? Do any of the standard LWJGL tests work?

Thank you for your help.
The regular beta4 works in windowed mode, the white screen is shown only in full screen mode.
I have included your second set of libs with my debug client and made it available for testing. I'll let you know about the result.

The modified library in lwjgltest2 shows the same behaviour as the regular beta4 lib: Windowed mode works ok, full screen shows completely white.
