I can't create a bugreport for Wingpanel, so in create it here. Feel free to move it.
---
After i resumed from suspend, wingpanel was at the lower half of the screen, moved to the right. (see screenshot) Before i suspended, i disconnected 2 external screens.
I can still click on the menu, but can't logout or reboot.
This is the first time i have this behavior and i think it will be hard to reproduce.
Here is the syslog, maybe it is helpful:
