Visual glitch while switching radio buttons

[jakubziebin]

Hello, We have a problem with the RadioButtons buttons located in the RadioSet. When switching the buttons, sometimes the situation with the video appears. issue_textual.webm Unfortunately, it is not possible to reproduce the problem with MRE (or it is so difficult). We do a workaround for this problem by adding a refresh call in the watch__selected method. Workaround code:

class MyRadioSet(RadioSet):
    def watch__selected(self) -> None:
        super().watch__selected()
        self.refresh(layout=True)

@jakubziebin Without an MRE it is going to be difficult to diagnose.

I see you are doing some kind of customization, can you at least let us know what you changed over the defaults?
