Video detailing the issue

When enabling "Show Seconds" in the Digital Clock widget it is constantly resizing and therefore moving the adjacent items on the panel.

1. Add a Digital Clock to a panel
2. Enable "Show seconds"
3. Put some other applet next to it (into the direction it will expand)

It resizes constantly, which causes adjacent applets to move

It should not affect adjacent applets just by changing seconds.

I'm not seeing this in Plasma 5.20. Can you reproduce it?

Looks like I missed your comment Nate. Well anyway:

Yes I can still reproduce this on 5.20.2.

Here is some info that might help, solve this problem:

First of all: Enable "Show seconds" and disable "Show date". That way the bug should already appear. If it does not appear you might need a font that has large enough changes between different digits. I use Fira Sans here so that might also be a factor.

As I switched my regional settings lately I don't experience this anymore directly, as the date line is now wider than the time, which "fixes" the problem.
Comment 4 Nate Graham 2021-08-12 16:12:23 UTC
Yeah we need to reserve room for the widest possible seconds string here.

I think I might have found a surefire way of replicating this bug. When you set the taskbar height to 36, it happens but none of the other 30's cause it to happen
Comment 7 Paul Meier 2022-05-07 10:52:32 UTC
Problem has appeared again with latest Plasma 5.24.5. If the taskbar height is set between 24 and 30 and date is set to show under the clock and with ISO format or long format.
The clock will move at every second with an ending "4".

applets/digital-clock: add a font size setting

This allows the user to choose between automatically determined font size
(the default, and the current behavior), and completely manual font settings.

The UI refactor and layout code changes necessary for this feature also
happily fix a few bugs along the way.
