The more channels and networks are added to the switchbar, the shorter the switchbar actually gets, until it's just a bunch of unreadable icons. I tried setting the pixel width to 0, and I tried setting the number of lines to 3.
And I don't mean the shorter the individual switchbar entries get, I mean the switchbar itself actually gets shorter with more entries.

Btw, the "Operating System" drop-down for bug reporting is out-dated: Windows 11 isn't listed.
