There we go I guess, I made a bare bones one because I doubt you need my entire 14MB resourcepack.
I cannot say for sure the issue will replicate, because my realm is offline due to some server issues or whatnot.

Steps to Reproduce:
1. Rename a disc in X.lang (X=Language of your choice)
2. Make a resource pack applying this new X.lang
3. See in game that the disc displays with the correct "new" information
4. Create a realm using this resource pack
5. See in game on the realm that the disc reverts to it's old default information.

Observed Results:
Discs do not retain information given in .lang when used on a realm.
They DO retain information when used in a single player game.

Expected Results:
Discs should retain information given in the modified .lang as they do on a single player game.

Yes this seems to be the same bug, thank you!
I did try to search for both wool and sheep pre-post, but did not find the any of the other posts...

Hopefully I did that correctly ?
Beds currently in use as of last session are at:
380, 64, 704
377, 64, 724
272, 64, 666
349, 71, 732

Hope this helps

Additional information I found:
I disabled my texturepack just to be sure, it changed nothing, paintings still fall.

Paintings only fall when the second player logs in near them, when they log in far away the paintings stay up.

Logging out does not affect the paintings.

Entering or exiting the nether seems to not affect the paintings, but may then be due to distance between paintings and portal?

Only some of my paintings seem to be affected, it seems localized to a certain chunk of my house as far as I can tell, nowhere else in the world have we seen this behaviour. Also not every painting will fall every time, it seems a bit random in that area,
But always one or more painting fall there.

EDIT: Paintings fall even when I the first player is 500+ blocks away.
Wich seems to narrow it down to an issue with the second player and that specific chunk?

Steps to Reproduce:
1.Play minecraft on laptop (win10) no issue.
2. Second player joins world from PS4.
3. Cry salty tears as paintings fall down, possibly due to issues with chunk borders or world loading?

Observed Results:
Paintings break and fall as objects.

Expected Results:
Paintings to stay on walls where placed.

I have added screenshots as requested.

I also have a short film on my phone where I can see the painting break off and fall to the ground when the second player joins, but it was too large to upload here.
