Task manager icon only icon spacing too big

On updating Plasma today to 6.3.1, my icons have all spread out on the task manager icon only panel.

Not by much, but it means that I only have to open a couple of unpinned programs and I’m out of space. The “small” spacing in options is still what I have selected, but it’s still a big waste of space. I’ve tried playing with the files in:

/usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/

specifically code/layoutmetrics.js line 14:

// return (taskFrame.margins.left + taskFrame.margins.right) * (tasks.vertical ? 1 : spacingAdjustment);
return 0;

But this hasn’t had any effect. Any suggestions please?

I’ve also gained a dark border on the panel which I’d like to not have.

In this instance please launch a few programs and take a screenshot of your main panel.
