Constrain Crop stopped working v 11.0.1

LR Classic CC, Windows 10 Home

Constrain Crop has ceased to work. See the white lines?  I've been having to manual crop after adjusting since the v11 upgrade, and 11.0.1 did not fix Constrain Crop.

I just checked that on my Win 10 system and also my MacBook Pro.  I'm not seeing the issue here. I tried it in the Transform panel like your example.

I have two suggestions you can try. Check the status of your GPU in the LrC preferences. If on, turn off and vice versa. Also try resetting the LrC preferences. Here is a link to the Adobe instructions for that.
