POP operator tab is all black

I tried installing both using the web installer and the full installer but the pop operator window is all black. Hovering over it shows the operator names below and I can click and choose them and drop them in the network but I can’t see where’s what.

Looks like you are using a modified OP Create dialog, this is probably causing some issues. We recommend uninstalling or disabling your add-ons to narrow down the issue.
