Short description of error
Not so much an error but had a cylinder with 60 subdivisions with bevel and subdivision modifier and blender closed.
Exact steps for others to reproduce the error
- Create cylinder with 60 vertices going round it.
- Add bevel and subdivision modifier.
- Make sure that the subdivision is modifier is cranked up to that undoing will take a lot of time after applying the modifers
- Apply the modifers
- Hit undo quickly a few times and try to select something in the viewport while the viewport is frozen.
