When I enter fullscreen on Linux only the upper left quarter of the screen draws anything and the remaining 3/4ths of the screen are black.
I spoke with LWJGL developers and they suggested that Minecraft may not be properly updating the viewport by calling glViewport and that this may me what is cropping the view.
For now I have to play with the window maximized.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
