Mobs and particles sometimes don't fully render behind stained or tinted glass

[^[Converted by HDconvert.com] Minecraft 20w49a - Singleplayer 2020-12-02 22-47-58.mp4]

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report (minecraft/crash-reports/crash-<DATE>-client.txt) here.

I've changed the title after finding out other mobs are affected. I've also added a crash report.

Only seems to be on graphics fast and fancy, not on fabulous. Also only when entity shadow is off.

Okay, so f1 seems to always make some mobs disappear behind colored glass when entity shadows are off. When entity shadows are on, mobs don't disappear behind colored glass, but the entity shadows do disappear. Smoke particles don't seem to render behind colored glass in any circumstance. Other entities like arrows are also affected, with and without entity shadows.

Nope, this issue appears to be fixed in 21w19a.

Reopening as we've managed to find recreation steps for this issue:

1. Use any graphics mode other than fabulous

2. Turn off entity shadows

3. Place a two high pillar of stained glass

4. Use spawn egg to spawn a cow behind pillar

5. Move side to side, every now and then the cow will disappear

I am able to confirm that this issue still exists in 21w19a using the reproduction steps provided by @unknown. I've attached some screenshots that demonstrates this issue.

Can reproduce in 21w19a with the provided reproduction steps.

Fix doesn't seem to have affected particles. Any graphics but fabulous, look at a particle behind tinted glass. I've attached an image example of a particle partially hidden by tinted glass.
