When using the Roboto 12 font as window title font, and rebooting, decorations become and remain huge (as long as one doesn't change the font size then reboot)
STEPS TO REPRODUCE
1. Choose the Roboto 11 font as title font
Immediatly after 1., decorations looked good. After 2., decorations get huge.
After 1. and after 2., decorations should look the same.

Please have a look at the following screenshots, taken in this order :

1. After setting Roboto 11 as window title font

2. After rebooting (with Roboto 11)
https://ibb.co/kky1DV (decoration became too large)
3. After 2. and setting Roboto 10
https://ibb.co/hra3Sq (as you can see the decoration remains huge)
4. After 3. and a second reboot and keeping Roboto 10

Clean install, KDE Neon up to date as of today. I tried with a clean user too. Using Breeze.
Oops, I mixed sizes up. The SUMMARY should obviously be :
"When using the Roboto 11 font as window title font, and rebooting, decorations become and remain huge (as long as one doesn't change the font size then reboot)"
Nah, it looks like that's indeed a bug in KDecoration. No one emits fontChanged.

[decorations] Emit DecorationSettings::fontChanged signal
No one emits DecorationSettings::fontChanged signal, so if you change
the window title font, then titlebars might look differently after reboot.
Currently, there are two places where we can emit that signal:
- in KDecoration library itself;
- and in KWin.
Because we would need to listen for a Plasma specific D-Bus signal, the
latter option is preferable.
Surprisingly, KWin's implementation of DecorationSettingsPrivate already
reacts to refreshFonts D-Bus signal (even though indirectly), so all
what we have to do is get the current window title font in
SettingsImpl::readSettings, and if it's different from the previous one,
emit DecorationSettings::fontChanged signal.
* Increased the size of the window title font, titlebars got bigger;
* Decreased the font size, titlebars got smaller.
