Public bug reported: After updating from 19.04 to 19.10 I noted that some apps don't redraw their window(s) correctly. Affected apps include (it seems) all Qt- based apps (including KDE and VirtualBox), as well as firefox/thunderbird.
Unaffected apps include emacs, chrome, xterm. The symptom is that an affected app will only redraw its window when another X window redraws its window. If there is no other window, then the app's window is not redrawn at all. This is best illustrated with a video, which shows the problem using konsole and kpat (both KDE apps) :- https://photos.app.goo.gl/hd7UtTt2k6Pn9GBLA I am using the intel graphics driver (no graphics card).
