Sorry, first subject title was plainly wrong.

 Hi,

 I have installed Lubuntu 20.04 on my laptop and xmonad doesn't redraw 
 it background. That is if I am on workspace 1 , and switch to a 
 workspace with no window, the background of the new workspace is made 
 by the windows of workspace  1.

 I do have some warnings  in xmonad.errors but  don't feel they are the 
 explanation of the problem I encounter.

 Would somebody have a workaround ? Not being able to use Xmonad would 
 be hard to bear.

 Best regards,

 Alain
