Logitech K750 and CMD-TAB (And CMD-`) Hotkey Problems

I have found that at long as I don't install the Logitech software, like the LCC, then everything works fine.

FWIW, Logitech no longer uses LCC. Their replacement is Logitech Options.

To clarify – I won't use their software. I've been using a G400s mouse for many years.

I use USB Overdrive in preference to the macOS mouse driver.

I truly hope is Logitech Options isn't perpetually buggy on the Mac like LCC, but I won't count on it.
