[MC-302561] Slime blocks are visible through solid blocks when viewed through transparent blocks while being pushed by a piston

When a stained glass block, a slime block, and an opaque/solid block are pushed by a piston, the slime block renders on top of the solid block when viewed through the stained glass block…

I would guess this generally applies to all semi-transparent blocks, but I could only showcase it in this specific setup.

I don't have it like that

As you can see in the first video, the bug did not occur during the first few piston pushes after the game was unfrozen, so it may be contextual.

Hi!
Thank you for your report!
However, this issue is Invalid.

Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.

Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
A world which had previously been opened with a modified client might be corrupted. Please try reproducing the issue in a newly generated world.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers like Hypixel, please contact them first as they run modified server software.

This occurs in a vanilla server as you can see in the videos below.

However, all the videos I have attached were recorded on a vanilla client.
