Changing UV smoothing mode in Subdivision Surface in geometry node does not refresh UV Editor View #98594

New Issue

System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.86

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
Subdivision Surface in geometry node have option for UV smoothing.
And UV editor have overlay option for Modified Edges, that shows modified UV.
However, UV editor is not refreshed in real time when that option is changed.

I uploaded screenshot gif animation.

3D View is updated in real time.
(Texturing is also updated in real time)
However, UV editor is not refreshed until view is moved by mouse dragging.
Here, lines for modified Edge are enhanced by changing Theme color to white.
(UV/Image Editor - Texture Paint/Modifier UVs)

(Ensure Blender is built with -DWITH_OPENSUBDIV=ON. Should be enabled by default for most builds)
Exact steps for others to reproduce the error

Open the attached file ModifiedEdges.blend
In the geometry nodes editor, change the UV smoothing option from "All" to "None"
BUG: observe that the 3D view is updated in real time, but the UV editor is not.

 (You can redraw the UV editor view by panning or zooming in the UV Editor View.)

Changed status from 'Needs Triage' to: 'Confirmed'

Can confirm, not sure if this should be considered a bug, as we already have similar missing redraws.

Please provide a very simple .blend file. That would help reproducing the issue much easier.

I uploaded here a simple .blend file

ModifiedEdges.blend

This is a snapshot of that .blend file.

Overlay option for Modified Edges is enabled,
and theme color for that is changed to white for clarity.
