Filter/Tree Size very small

I am testing the Query Studio first time and can nothing see. Please look at the picture. 

I take a look to the sourcecode and the comments are portuguese (Wagner, you?) ;-)

I have many problems with wrong sizes on my screens in many TMS-Tools 
(Desktop PC 2x 4k with 175%, Notebook 3240x2160 on 15" with 200%)

Can you check this please?

Best regards

We have fixed that, it's now released as 1.13.1 version. Demo is working, if you use it in your own application, you have to set TatVisualQuery.ItemHeight to 0.

Great, thank you.
