Summary: 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. BUG: 400980 FIXED-IN: 5.15.0 Test Plan: * Increased the size of the window title font, titlebars got bigger; * Decreased the font size, titlebars got smaller.
