I allow users to toggle my game's fullscreen mode from an ingame menu. When the fullscreen button is clicked, I call:

glWindow.setUndecorated(fullscreen);
glWindow.setFullscreen(fullscreen);

(fullscreen being a boolean variable, of course)

Sometimes this works fine, but often it triggers a lock exception (see below) and apparently locks up the animator (I use an FPSAnimator). Resize events still update my window, but the animator doesn't.

I do all my own logic from my GLEventListener's display() method. I tried disabling the animator before calling setFullscreen() and reenabling it afterwards, but it didn't help, probably since setFullscreen() internally calls runOnEDTIfAvail() anyway.

This is all on Linux/X11/KDE by the way, I haven't yet tested it on other platforms.

Perhaps I'm simply calling setFullscreen() from the wrong location. But in that case, where/when *is* the correct time to call it?
