Example fontconfig file
before.fonts.conf after.fonts.conf fc-match -v New crash information added by DrKonqi |

I'm unable to replicate this. I opened Fonts in System Settings, changed the Hinting to Medium, hit Apply, Closed System Settings. When I re-opened the Fonts section of System Settings it was still set on Medium. Tested via git build. Works for me too with my system's fontconfig, but the interaction of the KCM with the fontconfig file is such that it might be theoretically possible if the fontconfig file is configured a certain way. Need to re-test with the file that Jerry has provided. Jerry, are you able to please test with a new user account to ensure there's no user-specific configuration causing the issue?

I can reproduce this with a new user.
I only have Arch systems (x86-64 Arch and PineBook's ARM Manjaro) to test this on.
By default, they do not ship any config file linked (10-hinting-{full,medium,none,slight}.conf).
That's how I ran into this to begin with.
Manually configuring EITHER the local or global fontconfig files reliably allows me to change the setting afterwards in the GUI.
If NEITHER the local nor global fontconfig files set hintstyle, changes to the Hinting setting in the GUI are reliably not saved.
I've included the local fontconfig file generated by System Settings after step 6 (before.fonts.conf) and after step 11 (after.fonts.conf).
Steps:
1. Delete the link /etc/fonts/conf.d/10-hinting-none.conf which is the only global setting that sets hintstyle
2. Create a new administrator user via System Settings -> Users -> Add New User
3. Log out and log into the new user
4. Observe that ~/.config/fontconfig/fonts.conf file does NOT exist
5. Observe that the hint style is "Slight" in System Settings -> Fonts
6. Change the hint style to "Full"
7. Close and reopen System Settings
8. Observe the hint style is still "Slight"
9. Re-link the file `ln -s /etc/fonts/conf.avail/10-hinting-none.conf /etc/fonts/conf.d/`
10. Observe that the hint style is "None" in System Settings -> Fonts
11. Change the hint style to "Full" in System Settings -> Fonts
12. Close and reopen System Settings
13. Observe the hint style is now "Full"
Thanks for the information! Can you paste the output of `fc-match -v`? Thanks! Under what conditions? When the GUI is able to change the setting or when it is unable to? While the bug is manifesting. Created attachment 135430 [details]

New crash information added by DrKonqi
systemsettings5 (5.21.5) using Qt 5.15.2
- What I was doing when the application crashed:
I was simply browsing the system settings, I was trying to change the sub-pixel rendering. Sometimes it gets set to chosen value, but reverts to RGB after restarting the app, and sometimes it causes system settings to crash.
- Custom settings of the application:
none.

Created attachment 134734 [details] Example fontconfig file SUMMARY In System Settings, the hinting style cannot be changed from "Slight". Applying the changes and restarting the app reverts the field to "Slight". The only way to change this was to set a value in a fontconfig file first (either ~/.config/fontconfig/fonts.conf or /etc/fonts/fonts.conf). I don't know if its intended to, but setting "Xft.hintstyle" in an X resource has no effect. STEPS TO REPRODUCE 1. Remove any file in /etc/fonts/conf.d that contains "hintstyle" and the hintstyle section in ~/.config/fontconfig/fonts.conf 2. Set (System Settings -> Fonts -> Fonts -> Hinting) to "Medium" 3. Apply 4. Close 5. Observe (System Settings -> Fonts -> Fonts -> Hinting) is "Slight" 6. Observe "hintstyle" does not appear in ~/.config/fontconfig/fonts.conf 7. Link a fontconfig file that sets "hintstyle" `sudo ln -s /etc/fonts/conf.avail/10-hinting-none.conf /etc/fonts/conf.d/` (example attached) 8. Set (System Settings -> Fonts -> Fonts -> Hinting) to "Full" 9. Apply 10. Close 11. Observe (System Settings -> Fonts -> Fonts -> Hinting) is "Full" 12. Observe "hintstyle" does not appear in ~/.config/fontconfig/fonts.conf 13. Repeat steps 1 - 5 OBSERVED RESULT The setting cannot change when the setting has not been set by fontconfig files. EXPECTED RESULT The setting should change even if no fontconfig files set the value.
