Took me a while to figure out how to enable Wayland. Apparently
WaylandEnable needs to be set explicitly to true in custom.conf to
appear in the login choices. Running with it now... One thing I can say
is that it seems to have fixed a problem where my entire Gnome session
would crash when I tried to open a 10MP JPG.

Title:
  [radeon] Application windows in 18.04.01 go black but launcher is
  still visible

Status in gnome-shell package in Ubuntu:
  Incomplete
Status in mesa package in Ubuntu:
  Incomplete
Status in mutter package in Ubuntu:
  Incomplete

Bug description:
  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.
