Multi-screen layout broken after restart
STEPS TO REPRODUCE
1. Configure a multi-screen layout: The main screen is the laptop screen at
1920 × 1080. Furthermore, there is a secondary screen (external screen) at 1280
× 1024, who is on the left of the primary screen, top-aligned. (see config.png)
2. Configure a panel with window list on each screen, showing only the windows
of this screen itself.
3. Shut down and restart the computer, maybe various times.
OBSERVED RESULT
Often (but not always), after a restart, the layout is broken:
- The primary screen at the right shows a strangely cut background image. The
secondary screen at the left has no background image any more. (see
bugscreenshot.png)
- A right-click with the mouse on the left/secondary screen has no effect. No
context menu appears.
- The window list at the panel of the left/secondary screen does not show any
windows, even when you move windows to this screen.
EXPECTED RESULT
- The background image is correct on both screens.
- A right-click with the mouse on the left/secondary screen shows the context
menu.
- The window list at the panel of the left/secondary screen shows all windows
that are on this screen.
