mingus-switch-to-playlist causes rendering issues with some packages

[kahrkunne]

Related to ch11ng/exwm#259.

Tl;dr: The following code in mingus-set-NP-mark is problematic:

  (save-window-excursion
    (mingus-switch-to-playlist)))```

This code basically relies on switching buffer and then switching back so fast that it's never rendered, but this causes problems with a few packages. Personally, I've experienced trouble with EXWM and ace-window.

Thanks for reporting this.

Does commit 9963cd9 fix your issue? It should now update the now playing mark only when the playlist is actually visible.

It only ever updated when the playlist was visible to begin with. Said commit does not fix the issue.
