The game renderer can corrupt when toggling fullscreen or opening an inventory with the OpenGL rendering backend

When toggling the Fullscreen Mode on and off, the game screen corrupts and gives off a very pixelated, grainy screen effect. This effect remains permanently on the screen when switching between worlds and pausing the game.

I can confirm that this bug only exists only in 26.3 Snapshot 2.

Steps to reproduce the bug:

  1. Create a world

  2. Pause the game and go to Video Settings

  3. Toggle Fullscreen on and off

  4. Exit the game settings, exit your newly created world, and join another world (Additional Step)

Expected Result:

The game screen should remain normal and unchanged as usual

Actual Result:

The game screen becomes pixelated and grainy and permanently remains like that until you have to restart the game entirely.
