Hi,
22.04 Jammy, here. Detail but eye catching, in the wrong way.
If seconds are enabled in clock applet in a panel, depending on the width of second numbers, it constantly « moves » all applets on the left…
You can see the little offset far left, just imagine it almost each second
And it does not take account of space characters I may place before or after the string - which is %a %e %b %T s%V
here ( hence the use of spacers. )
Same with Calendar applet, but at least this one « accepts » space characters.
Seems those applets don’t have a fixed width or dynamic padding or centered content, sort of ?
Those « moves » do not occur in 20.04 ( wrong, see below. )
