Qtdragon - blurry main screen during manual tool change

During manual tool change dialog pop-up, main window goes blurry. In most cases it does not go back into standard (non-blurry) after a manual tool change dialog is closed.

I was trying to find it within the python code of qtdragon and qtvcp, but because my poor knowledge of qtvcp source, I was not able to.

Can you advice, how to disable the main window blurry feature?

it seems I perhaps found it. Was looking into a wrong part. css does it, looks like.

Sample of stylesheet changes:

Sounds like you are not using Qtvcp's manual tool change dialog?
Though I would have thought it would work properly either way.
