Short description of error
On an addon I subscribe to the depsgraph update handler. The handler grabs some data via bmesh - its not changing anything.
Testing with the default cube - everything works fine, one can move uvs around without issues.
But on a cube with 6 subdivision (24k verts) - moving uvs results often in corruption and soon blender crashes.
Interesstingly doing regular vert transformation in the 3d view doens't create any issues as far as I can tell.
Exact steps for others to reproduce the error
- load attached blend file
- run script in text editor (review script - its really simple)
- enter edit mode on the cube
- make a uv selection
- try moving uvs around
