[xmonad] windows overlap the task bar

[Alain Bertrand]

Hello,

I have been running xmonad for years on my desktop (Debian 7, then 8 and
9) and I am highly satisfied: this is the only one that prevents me to
"try another thing"!

On my laptop (ubuntu 18.04), the windows overlap the task bar though I
use exactly the same xmonad.hs file as I do on my desktop.

Could you help me ?

TIA

Alain
