Rendering-fighting caused by custom material

A rendering-fighting glitch occured when applying the custom material that the stencil test was applied on to a model with a transparent textured surface.

I made a glow outline for my custom entity and it looked perfectly with Vibrant Visuals (I1 in attachment).

However, the glitch occured when I change the graphic mode to Fancy (V1 in attachment).

Then, I created a new flat world to test if this glitch occured again and it still occured (I2 in attachment).

But surprisingly, the frequency of the glitch decreased. I guess it was because the world was new.

This bug is relative to MCPE-219845.

Step to Reproduce:

1. Create a new world or use the world provided from this bug report.

2. Apply the addon provided from this bug report.

3. Change your graphic mode to Vibrant Visuals.

4. Spawn a Wall Collision entity and enter the command “/event entity @e zombiend:add_glow”.

5. Change your graphic mode to Fancy (or Simple).

Expected Result:

In both graphic modes, the entity rendered correctly, and no render glitch.

Observed Result:

The entity rendered correctly with Vibrant Visuals, but the glitch occured in Fancy (or Simple) graphic mode.
