Semi-transparent square behind crosshair when anti‑aliasing set to 2+

Since the 26.30 update, enabling anti‑aliasing at 2 or higher causes a faint semi‑transparent square to appear behind the crosshair. This issue did not occur in earlier versions, where the crosshair background remained fully transparent regardless of AA settings. The bug seems specific to PC (Windows GDK build), as other device like mobile doesn't expose anti‑aliasing options and doesn't show this behavior.

Steps to Reproduce:

1. Launch Minecraft Bedrock 26.30+ on PC

2. Go to Settings > Video > Anti‑Aliasing

3. Set Anti‑Aliasing to 2 or higher

4. Enter any world

5. Look up to the sky to observe the crosshair easily

Expected Behavior: Crosshair background should remain fully transparent at all anti‑aliasing levels.

Actual Behavior: When anti‑aliasing is set to 2 or higher, a faint semi‑transparent square appears behind the crosshair. Meanwhile, when set it to 1, the crosshair background is correctly transparent.

Notes:

• This issue only happened on Windows.

• Began with 26.30 update, did not happen in earlier versions.

• Screenshot attached for visual evidence.

Additional Note:

The semi‑transparent background behind the crosshair is clearly visible on PC monitor (I’m using laptop), but it’s pretty hard to see it when viewing screenshots on other devices like mobile due to differences in display glass, pixel density, and rendering pipeline. Please test directly on PC to confirm visibility.
