Comment 1 Aurélien COUDERC 2021-02-06 20:55:15 UTC 
In fact it depends on various factors like the scaling and the exact size of the panel. For example I’m using 125% and it’s broken when the panel height is in [30px,40px] but neither below or above.
And for 100% it is broken in [44px, 54px].

What seems to happen is that:
- the K menu icon is not scaled continuously but by by notches, I guess to use only available bitmap sizes and have it always crisp
- when the panel is made taller than the immediately smaller icon size that can fit, padding is added around the icon
- the padding is not clickable (neither on the left nor on the top side in fact)

I can also replicate this in Kubuntu 21.04 development release with the 5.21 beta package I uploaded.

Already fixed in the final version thankfully.
