virtual box display problem
SUMMARY
I have a dual display setup with monitors of different resolution.
I have global scaling enabled and set to 175 %
when I start some applications like vlc, virtualbox, dragonplayer, kate the
content of the application is not drawn properly and the content of the window
(menus button etc) is unusable/unreactive. Resizing the window does not
refresh the window (see ttached screenshot of virtualbox
now when I disable one screen OR set the global scaling to 100 % the paint
problems go away.
when I mess with the backend renderer the problem does not go away.
setting the scaling to 100% and using the fonts to scale is a workaround but it
does not increase the size of visual elements like scrollbars which remain
rather small.
