STR:

  1. Start Firefox with GDK_BACKEND=wayland on Ubuntu 18.10.
  2. Set privacy.resistFingerprinting = true.
  3. Maximize window.
  4. Restart Firefox.

The window is initially maximized on startup before being unmaximized which causes it to be garbled due to being resized (Bug 1468911) but it remains this way. Have to switch focus to a different window to get it to redraw properly.

How do you restart the browser?

How do you restart the browser?

The window close button or Ctrl+Q, both produce the same result on Ubuntu 18.10.

I can no longer reproduce this in latest Nightly.

Workaround is to set browser.startup.blankWindow = false.

I cannot reproduce this since upgrading to Ubuntu 19.10 with Nightly builds after the regression, it appears to have been fixed upstream.
