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.
