Starting with the introduction of RenderDragon, UI elements are affected by anti-aliasing. This causes unwanted side effects, such as blurry menus and problems with transparency, such as the crosshair losing transparency, staying completely white, and the hotbar rendering differently.

How to reproduce:
-Set the anti-aliasing setting to x1. Observe the various UI elements.
-Set the anti-aliasing setting to x2 or higher. Observe the same UI elements again.

Expected results:
Menus look sharp. The crosshair is transparent and inverts colors. The item hotbar maintains its proper transparency.

Actual results:
Menus appear to be blurry. The crosshair is a solid shade of white and does not invert any colors. The item hotbar transparency is altered.

MCPE-58826 is a consequence of this issue, but the issue is not exclusive to the crosshair.
