SUMMARY I believe there was a dialog box in the earlier versions of the System Settings GTK control panel that enabled you to set the size of fonts for GTK applications. I no longer see such an option in recent versions. Operating System: Kubuntu 22.04 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 Kernel Version: 5.15.0-33-generic (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-2410M CPU @ 2.30GHz Memory: 11.6 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 3000 STEPS TO REPRODUCE 1. Go to System Settings > Appearance > Fonts 2. No GTK option. 3. Go to System Settings > GNOME/GTK style 4. No option to set font size. OBSERVED RESULT No option to set GTK font size. EXPECTED RESULT Dialogs to set GTK font size.

GTK font settings are synced with Qt ones and there's no need to set GTK settings separately.
Indeed there was; that was before we automatically set the GTK font from your general KDE font settings. Now you only need to set the font size in one place to have a consistent experience, rather than two.
Could you please bring the option back? This is the first time in decades when I'm unable to have the same font in Qt and GTK applications, because KDE doesn't let me have it. I'm using the default Breeze theme with the default Noto Sans font and the default 10pt size. And not only is the font size in GTK applications visibly (and measurably, I made a screenshot to compare) bigger than it is Qt, but it looks like the font itself is different in GTK, more narrow, it doesn't look like the rounded Noto font used in Qt. I know GTK4 uses very different (and vastly inferior, IMO) font rendering from GTK3, GTK2 and Qt, but I'm using GTK3 and GTK2 apps, and I've never seen any difference between font rendering in Qt and GTK2/3 until now, when I upgraded to Kubuntu 22.10 with Plasma 5.25.5. So when KDE is unable to set the GTK fonts properly, I would still like to have the option to set it myself, to have a consistent desktop. By the way, this is one of many cases where KDE is removing or lacking crucial options because it mistakenly thinks it does something properly and therefore no settings are needed.
It sounds like you're suffering from a bug. Please submit a new bug report describing it in detail so we can investigate it and fix it so that it works automatically, which is the intention. Thanks!
