qubes-manager doesn't open

[Pili21181]

Qubes OS version:

Version R3.2

Affected TemplateVMs:

Qubes VM manager
VM windows

qubes-manager open but don't work properly, buttons missing, can close it only by console.

when i open an app in VM like firefox it works but the whole upper line with closing buttons is not there and it's also not possible to move the windows to a random place, can only move it to another screen by moving the tab.

I get this error :

CalledProcesserror: Command '['/usr/bin/wmctrl', '-R',
'Qubes VM Manager'[' returned non-zero exit status 1

This is most likely a bug in the Qubes Manager

line no.: 2024

I tryed to reboot, kill manager and restart by console in dom0 with no success it's also impossible to unlock key ring for VPN access as it dont write the password when i type it.

Help will be really appreciated as my knowledge is limited and searching google doesn't lead to any results.

Thanks in advance.

Cheers.
