Comboboxes in IDE and programs not work

[gaucho <64xcode@xxxxxxxxx>]

Hi

The comboboxes do not work correctly in IDE (in gtk mode), also the
programs.
Normally I use GTK (ubuntu) then I use QT5 & 6 it works but the
selection in the code window has a strange behavior as I can't select a
variable to see if value and stuff like that, it's really very
annoying.
Any idea? is it a bug?

Best regards

Martin
