NamedScratchpads Freezes Xmobar

[ybenel]

Problem Description

So recently i have updated my xmonad/xmonad-contrib (0.17.1) i noticed toggling on/off any of my scratchpads causes xmobar to freeze, upon restarting xmobar it doesn't behave as it should until (Restarting The Session).

Steps to Reproduce

• Use Xmonad with xmobar
• Set up Any NamedScratchPad
• Toggle it on then off and observe

Configuration File

Please include the smallest full configuration file that reproduces
the problem you are experiencing:

import XMonad.Util.NamedScratchpad

myScratchPads :: [NamedScratchpad]
myScratchPads = [ NS "terminal" spawnTerm findTerm manageTerm ]
 where
  spawnTerm  = myTerminal2 ++ " -class 'Term' -fn 'Cascadia Code' -fa 'Cascadia Code'"
  findTerm   = (className =? "Term")
  manageTerm = customFloating $ W.RationalRect l t w h
             where
               h = 0.5
               w = 0.5
               t = 0.2
               l = 0.2
-- Hook 
 manageHook = namedScratchpadManageHook myScratchPads

-- Shortcut

How do you restart xmobar? Your full config uses the deprecated piping method of passing data to xmobar, so this is probably expected? Can you perhaps try using https://xmonad.github.io/xmonad-docs/xmonad-contrib/XMonad-Hooks-StatusBar.html instead?

Thanks for mentioning the depracated piping method switching to StatusBarHook fixed the issue.
