Everytime I restart my plasma session, the option to hide titlebars for maximized windows is reset to no and I need to manually enable it back.
Forgot to include version info: Operating System: KDE neon 5.19 KDE Plasma Version: 5.19.2 KDE Frameworks Version: 5.71.0 Qt Version: 5.14.2 Kernel Version: 5.3.0-61-generic OS Type: 64-bit
I also have this problem, but it just started when I updated: frameworks 5.84 to 5.85 gear 21.04 to 21.08 plasma 5.22.3 to 5.22.4 Unfortunately I didn't test these separately as I was away and they all updated at once. On the older version it works, on the newer version it doesn't. This is reproducible on 2 of my machines both running KDE on Arch.
