Rendering of the F3 menu significantly more performance intensive since 25w15a

F3 menu GUI rendering has a much more significant impact on performance than it used to.

In my test the FPS is 35% lower with the F3 menu open in 25w16a vs 1.21.5

This stands in contrast to general improvements in GUI performance (see comments under MC-233604)

Reproduction Steps:
- Do the following in 1.21.5
- Create a void superflat world
- Turn off clouds to isolate the pefromance impact from their changes (MC-296806)
- Press F3 then F1 to hide the GUI
- Wait a few seconds
- Press F1 to unhide the GUI
- Take note of the FPS value on the same frame when GUI was unhidden
- Take note of the FPS value after a few seconds with the GUI visible
- Repeat the steps in 25w16a

Observed Results:
- Between 1.21.5 and 25w16a the FPS is pretty similar with GUI hidden
- In 25w16a the FPS is significantly lower with the GUI not hidden

Expected Results:
- There would not be a significant regression in GUI rendering performance
