when I do a UV flatten I am getting a popup on Houdini console showing RenderPick(). this happens when I move my mouse in scene viewport. what is this,how do I stop it?

SideFX was able to reproduce this issue and they have created a bug report. this occurred in 17.0 and 17.5

here is how it occurs:
- create box, type polymesh
- in scene view “C” select UVFlatten
- select edge then “N” to select all
- select edges to flatten
- hit enter

when you move mouse in scene view you get a popup with RenderPick()
