Switching fullscreen/windowed crashes and bugs

[Rock_D]

Switching to fullscreen and then back to windowed gave me an VM access violation for my own program. When looking to replicate the error I found that the FullscreenWindowedTest webstart demo gives an Exception that might be related if you switch to windowed and then back to fullscreen. Sometimes it didn't give the exception, but it just crashed, giving me the same vm access violation that I got with my program (posted at the bottom).
The console log showed this (for the exception):
org.lwjgl.LWJGLException: Could not make context current

OrangyTang on the lwjgl IRC tried the fullscreen webstart demo as well and he also got the exception (not sure about the crash).

My system:
Windows XP SP 3
NVidia 8600 GT
forceware 185.85

Context switch is something very obscure.... Therefore full-screen switch should be requested on the same thread that invokes rendering (update()).
Either use Swing Event Thread or a custom TimerTask, but it has to be the same Thread that invokes Display.update(). it is generally Swing that's best for rendering tasks.

[Rock_D]

FullscreenWindowedTest is very simple. It's just one thread that creates the display, then updates the screen in a loop, nothing else, so it couldn't have been another thread calling the update.

[Ciardhubh]

Same exception here (Win XP SP3, Nvidia GT8800).

The crash happens when going from windowed mode to fullscreen mode.

A workaround seems to be to destroy the display before changing the display mode and then creating it again, e.g. :

       if (Display.isCreated()) {
            Display.destroy();
        }

        Display.setDisplayModeAndFullscreen(mode);

        Display.create(); // Remove .create from initialize()
        glInit(); // Can result in square being off-screen

Then again, how much of a workaround is this really? You probably have to reload textures, shaders, GL-states, etc. again.

[broumbroum]

I'm doing some similar "frame-cycle" using AWTGLCanvas.
WINDOWED_MODE -> First close -> dispose -> create a new Frame -> FULLSCREEN_MODE.
But since it doesn't close the AWTGLCanvas, the context may be kept alive. I simply had to correctly implement addNotify() removeNotify() to start and stop rendering.
I'm publishing today JXA 3.3, where it may be found RenderingScene.
