Public bug reported: This is a fresh install of 2020.04. Issue is that the display routinely gets corrupted and flickers with blocks of previously open windows. If left without a restart, the system menu text will get replaced by odd characters and system dialog boxes will not display, buttons for the dialog boxes will briefly appear with no text when cursor is over them. Very occasionally, the system will stop responding to the mouse and keyboard after clicking an icon on the dash.
