OptiFine FPS counter doesn't work, but hiding it completely breaks the video output

[fffelix-jan]

Describe the bug When playing with OptiFine on 1.16.5, the OptiFine FPS counter shows as a solid white rectangle, and if it's disabled or the F3 screen is not shown, the screen only shows a solid colour.

To Reproduce Steps to reproduce the behavior:

1. Install Impact 4.9.1 for 1.16.5 with OptiFine on Windows 11
2. Enable OptiFine FPS counter
3. Play the game, the counter shows as a white rectangle
4. Disable the counter, now you can only see a solid colour across the entire screen and you can't see anything else Expected behavior FPS counter and game works normally. (I installed the same version of Minecraft, Impact and OptiFine on macOS 10.14.6, and it worked fine.)
