Public bug reported:
Intermittently and randomly, all application windows will go black. They
are still there, and can be interacted with with keyboard shortcuts or
if you know where to click with the mouse, but they are not drawn.
The launcher itself is still displayed.
Clicking Show Applications briefly draws the application window before
switching to the background and application icons. The application icons
are shown correctly. Selecting one switches to a black window for that
application. The application window is again briefly displayed when
dismissing the application icons by again clicking Show Applications.
TTYs work normally.
Killing gnome (from another TTY) and allowing it to relaunch results in
a normal display again.
This is being seen on an hp 6910p. This system also exhibits a corrupted
lock screen since upgrade to 18.04.01. Neither of these behaviors were
seen during two years running 16.04.01.
Chrome is being used. Current 70.00.3538.77 (64-bit). Chrome is the most
commonly used application on this machine, so it is possible that the
behavior is being triggered by Chrome, however, the behavior affects all
applications, including system applications like software update and
terminal.
