Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Win10, x64
Graphics card: NVidia 1050 4G Ti
Blender Version
Broken: 2.80 beta, 2019-02-24
Short description of error
Trying to select a texture island and then trying to rotate, scale or move it, freezes blender.
It seems to do something, the app consumes some cpu.
Important: Selecting all unwrapped vertices and then trying to manipulate them works flawlessly.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
Thank you,
Stan.

Disabling proportional editing will avoid the issue, it's just really slow on high poly UVs.
I guess there is some O(n^2) code in there.

I have re-triaged this report and can not reproduce it.
Can you please check if this is still an issue in latest build?
