Help correcting gimp font size

I'm using X1C gen 7 4k, xfce, lightdm, uefi & grub install > Arch wiki wrote: > > Gimp 2.10 To fix toolbar icon sizes, update > Preferences->Interface->Icon Theme->Custom icon size to huge or other > value.

You can also try using gimp-hidpi > (installation instructions are outdated and refer to version 2.8, in > Gimp 2.10 the theme should be installed into > ~/.config/GIMP/2.10/themes/) I've done all the above to no avail, nothing changed. I'm not sure where to go from here. What I did exactly was: 1. changed the settings in preferences and made the icon size huge. 2. mkdir ~/.config/GIMP/2.10/themes/DarkHighDPI 3. from within /usr/share/gimp/2.0/themes/Dark I sudo cp -r gtkrc ui ~/.config/GIMP/2.10/themes/DarkHighDPI 4. I edited the gtkrc file with sans 30 for both the gtk-font-name and font_name 5. Then from within the gimp program again I changed the theme settings to DarkHighDPI 6. rebooted my laptop started gimp, still no change. 7. I restored a timeshift backup to revert all changes I had made.
