Can't see this anywhere, but if a duplicate exists, please point me in the relevant direction. The other issues related to fullscreen seem unrelated.

Reproducing the issue:

Originally noticed on 19w02a. Also tested and reproduced in 1.13.0 & 1.13.2 release ... but can not be reproduced using the 1.12.2 release.

If I launch the game in windowed mode and then toggle full-screen mode, the game crashes.

If I launch the game in full-screen mode, and then toggle it to switch to windowed mode, it works fine. But toggling again to return to full-screen crashes the game.

It's reproducible 100% of the time so far.

Reproduced using keyboard shortcut (custom: F12), and also the button found in the settings UI. Both methods trigger the issue.

At this point, I haven't even opened a world - I'm simply sitting at the menu screen after having clicked "PLAY" in the launcher.
