I used Mint for a long time, I like it and Cinnamon. My laptop at home is running LMDE (Linux Mint Debian Edition), which is not based directly on Ubuntu like “normal” Linux Mint, and it works great.

I recently set up my desktop with Debian and KDE Plasma and think that will be my standard build moving forward. I have some home servers that are running Ubuntu and I was planning to rebuild with Debian anyways, so a Debian baseline across all my machines makes sense and should be easy to maintain.

The conventional ‘not’ would not behave differently for the two non-zero values. Insidious.

I had a similar problem, literally just fixed it. I just logged out completely and manually logged back in. Seems fine now.
