Paintings Detaching Themselves From Surfaces

I have recently encountered a bug (or tech limitation) where paintings are detaching themselves from affixed surfaces and dropping to the floor as loose items until they are either picked up or de-spawn.

For example, I have a Woodland Mansion that I have converted into a kind of hotel. There are many rooms, and I have somewhere around 50+ paintings hanging on walls throughout the mansion. At some point, I began to notice paintings were disappearing. As I re-hanged those paintings, more would disappear from other places. I even caught a few of them as loose items on the ground below where they were originally hung. I have confirmed the problem is persistent on my Windows PC and Apple iPad.
