Panel Spacers Regression in Plasma 5.8?

Anyone noticing the panel spacers in 5.8 can’t be fine tuned and decreased in size below a centimetre or so?

Well, I haven’t noticed this myself as I don’t use spacers, but it is a known problem:

Should be fixed in 5.8.1 which will be released on Tuesday.

ah, right, good news. ta.
