System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.47

Blender Version
Broken: version: 3.1.2, branch: master, commit date: 2022-03-31 17:40, hash: cc66d1020c
Worked: (newest version of Blender that worked as expected)

Short description of error
When I Work with Multiple Objects with Modifiers like "Bevel" "Solidify" "Subdivision Surface" and I go to Edit Mode to do Some UVs, The Overlay Explode, Most of the time, as if the UVs were terrible.
The Pattern Changes with UV Sync, when changing the Select Mode in the UV Editor (Vertex, Edge, Faces).

It's a Bug I did not have with version 3.0 or below

Exact steps for others to reproduce the error

Open the blend File
Select All
go to Edit mode and you should see weird things happening in the UV Editor.

Sometimes the bug doesn't show, if it doesn't, i usually spam Tab or change the Select mode in the UV editor multiple times (1,2,3)

The File
UV_Explode_Bug_3.1x.blend

Screenshots :

Bug :
When Converting to Mesh (Apply all Modifier)

Hope You Will Fix it ! You made the greatest software Thanks !

I can confirm this on version 3.1.2. This only happens when GPU subdivision is enabled.

This looks a lot like #96372 (UV Editor doesn't work when GPU Subdivision in the Viewport is enabled), could we check if this is still an issue with a 3.2 build from https://builder.blender.org/download/daily/?

Philipp Oeser changed title from ~~UV Explode with Modifier Stack 3.1x~~ to GPU subdivision: UV Explode with Modifier Stack 3.1x

I think that it is the exact same bug, just tried with today's Build (April 12) and the bug is still happening

Yeah, can actually confirm.

@kevindietrich : mind checking? seems like fix for #96372 was not enough
