Can reproduce with certain amounts of space for the task manager widget. Introduced with https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2239.
Comment 2 Bug Janitor Service 2024-05-12 14:29:50 UTC 
A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2246
Comment 3 dmatteo002 2024-05-12 17:25:08 UTC 
I tested the open merge request and it indeed fix the issue.

I still have an issue with icon size while switching virtual desktop or while opening app, not sure if it is relevant. I'll add a video of the other issue as an attachments. What happen is when app change state from closed to open in the task manager, it sometimes get a size of zero (i think) for just a frame or so and then revert to default sizing.

If it isn't relevant I'll open another bug report for it.

applets/taskmanager: Fix launcher icon widths when in icons-only mode

Commit d1b33d1a9dc872e9a2af042152d6ab5ed2617e4e introduced logic to use
height / num_rows as the width for launcher-type (no open windows) icons. This
makes sense for Icons-and-Text TM, but leads to incorrect widths in the
Icons-only TM.
