QT range knobs dissapear

GNU Radio

I updated to 3.7.2 and found many improvements !
(Keep up the good work.)

But this little problem with QTrange knob’s stay.

  1. Create a QT GUI Tab Widget, named ‘tabs’
  2. Create 2 QT GUI Range blocks, both of type ‘knob’

Try to align them next to each other;

tabs@0:0,0,1,1
tabs@0:0,1,1,1

The result is an empty tab.

I must be doing something wrong…
