Similar to #980, I cannot reproduce it with debian9 py2qt4 , debian9 py3qt5 or debian10 py3qt5

So, just to try to understand:

Is this 100% reproducible in your platform?

Yes.

what steps do you do to create the panel?

Just from the menu: Panels -> New Panel

how did you install your pyqt and tango (and which versions?)

Is the same environment as in #980, which means, PyQt4 and Tango are installed via RPM package. The one for PyQt4 is the one provided by the CentOS base repository, the Tango and PyTango RPMs are the ones provided by the maxiv repository.

Versions:

CentOS 7 Tango: 9.3.2 and 9.3.3 PyTango: 9.3.0 PyQt4: 4.10.1
