LWJGL, minecraft, ubuntu 12.04 and exiting fullscreen.

[javajames]

To clarify, i'm posting this here because i believe the problem to be a bug with LWJGL and not minecraft. And i have tried updating LWJGL, that fixed a problem i had with full screen lagging but not this other problem.

Im running ubuntu 12.04 with linux 3.2 (generic) 64bit, with a AMD radeon 6870 and the 12.6 catalyst driver release. I'm having a very irritating problem with minecraft; when you exit fullscreen, or quit the game from full screen.

Full screen works fine, but when i leave full screen with the game running, the window goes black and extremely laggy/not usable.

If i quit the game from full screen my whole screen goes pink and into rectangles. And i have to force relog or restart the machine to fix this.

Has anyone else come across these problems, or should i test this in another LWJGL app (if so what/where.)

Try some of mine (http://www.puppygames.net) and see if they do the same.

Ok this is really wierd, if i toggle fullscreen off, i get black screen game. Toggle it back on and black screen full. Then toggle again and perfectly normal windowed??? Add infinity? So all i have to do is double tap F11 and im good, and tap once to reenter. But still kinda strange. Possibly patchable with a basic MC mod

Scratch that, that makes it worse because it looks like theres a 1/4 chance of going glitchy screen and not being able to return to the OS if i do that >.>

I'm using Ubuntu 12.10 dev with a GeForce 8600 GT (NVIDIA driver 302.17) and LWJGL 2.8.4. Minecraft doesn't provide an option to enable fullscreen mode. How are you enabling it? I'm using OpenBox (at default by pressing F11) to enable fullscreen mode. Toggling fullscreen mode and closing Minecraft from fullscreen mode doesn't make any problems on my system.
