Hello. I am unsure where to post this, but System Settings seemed like the logical place.

I have been using KDE on and off for over 10 years. I recently started using it again about a month and a half ago. Everything has been stable and working great, but within the last week, fonts for certain applications have certainly been appearing as small. I don't know what triggered this change.

Firefox, thunderbird, blender are apps I've noticed so far.

At first I thought it was a gtk settings problem somehow being reset. GTK-chtheme and qt font settings were all set to what they should be, at 28 or 32. I logged out, logged into gnome, and the font size appeared as it should be. So I think it's something in KDE specifically.

gtk-query-settings returns a font of Sans 10, but I am unsure where this is reading its settings from.

Any help would be most appreciated. Thanks!

Could you give some more precisions about your exact Plasma version and distribution?

Also what did you do before you noticed the change?

Many thanks for the response. I am unsure what I could've done to effect this. I haven't done an apt-get upgrade in quite some time. To complicate matters, I have been out of town for the week so this is the nasty little surprise that I came back to.

ubuntu 19.10
Plasma 5.16.5
KDE Frameworks 5.62.0
Qt 5.12.4 (built against 5.12.4)
The xcb windowing system

I can cut the tails of root and user's bash history if that would help?

Did you check your settings in System Settings -> Application Style -> Gnome/GTK application style? You might need to tweak something there.

FWIW: There is Plasma 5.17 in the Kubuntu backports since quite some time, might be an idea

So in all of the gtk config settings, the fonts were their proper size at 32. Changing to 28, then back to 32 oddly restored the proper font sizes. Bizarre. Much thanks for the help.
