I added a video to the ticket.

Can Xojo please put attention on improving Mac applications built with Xojo

There are several areas where I hope that Xojo will put their attention on next.

Yeah, we have been working on it… and looks like the bug has been squashed; just some more testings from our side.

Thank you so much for reporting it @Valdemar_De_SOUSA !!

Thanks to you @Javier_Menendez
Good job

I have revisited this bug once more - when you set background color of window (to be used as base for PopOver) the listbox bug hits again…

[Pawel_Soltysinski]

it turned out that the problem has a wider scope on MacOS; Javier Menendez registered bug:
