Game cannot reliably go fullscreen. When playing, pressing F11 or changing the "Fullscreen" setting in the Video Options sometimes fails to put the game in fullscreen, returning to windowed mode after a short delay. The screen blanks as when going fullscreen successfully, but the windowed mode returns immediately.
Only happens when an actual game is running. Doesn't happen at the title screen, happens when the in-game menu is accessed (via ESC).
It often takes 5-10 switches (either through options or F11) to get to fullscreen. Opening menus, defocusing and refocusing the game window and other voodoo might help, but not reliably.
Possibly related: Sometimes when the fullscreen mode is entered, the player is unable to turn around more than a fixed amount (as if the cursor was confined to the earlier, small window or went outside and did not register).

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.
I'm a developer and am willing to further investigate this issue if needed.

Thanks, I'll update.
Though I hightly doubt it'll fix this age-old bug.

Take a look at MC-2067
While fullscreen usually crashes on my Macbook, I can also (unreliably) replicate the cursor/turning thing.

Thanks, I will check MC-2067 out.
It did not come up come up in my searches before posting this bug (rather got the fullscreen crash ones).
I will investigate further.
So, reading various topics, it looks like this might actually be a WM/driver/lwjgl issue even though it's age-old.
What bugs me is that it doesn't happen at the title menu so there is something in the game code that's triggering it.
I found something. There's a function calling Display.setFullscreen() from LWJGL, which usually gets called after a check for F11:
if (Keyboard.getEventKey() == KEY_F11) { function(); }
On the occasions where this bug happens and I can't get fullscreen for more than a split second, the same function also gets called from somewhere else, doing a Display.setFullscreen(false) on top of the earlier call. That somewhere else is around a Display.isActive() check.

Is this still a concern in the latest Minecraft version 13w48b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
It seems like the problem in the title is gone.
However, the "cursor confinement" issue is now 100% replicatable. (But can be worked around by freeing the cursor by opening a menu (ESC) before going fullscreen – also at 100%)
Feel free to resolve the issue.
I will open another one for the cursor or comment on an existing report as soon as I have the time.
