I just wanted to add a temporary workaround for those who stumbled upon this bug report, building off Kevin Barry(barryk)'s post and Archwiki's Gimp 2.10 section from the HiDPI article (https://wiki.archlinux.org/index.php/HiDPI#Gimp_2.10)
I'm using a 15.6" 4k screen, so you should adjust your values to best work for your case. I followed these steps from archwiki: "To fix toolbar icon sizes, update Preferences->Interface->Icon Theme->Custom icon size to huge or other value (This is the bug here-- this bit doesn't work as intended. For now move the scale up to huge and get to the next section) If menu fonts are still too small you can update an existing theme by copying it from /usr/share/gimp/2.0/themes into ~/.config/GIMP/2.10/themes/ and changing gtk-font-name and font_name in gtkrc into something bigger like Sans 16. Then select the new theme from Preferences > Interface > Theme. When copying make sure to rename the new directory into something different from the original name (example Dark > DarkHighDPI)" Once you've made the theme copy, paste the edits that Kevin Barry has proposed into the ~/.config/GIMP/2.10/themes/DarkHighDPI/gtkrc text file in the # Set GTK settings section, but with the following values: gtk-icon-sizes="gtk-menu=48,48: gtk-button=48,48: gtk-small-toolbar=48,48: gtk-dnd=48,48: gtk-dialog=48,48" In my case of a 4k 15.6" screen, changing the font size to 16 and the various gtk sizes to 48,48 worked to make the huge setting the biggest. If you have a different ppi, try playing with multiples of 16 and see if you get a setting that works for you. The benefit of this approach over Kevin Barry's above approach is that no other application is affected -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1817389 Title: GIMP icon sizes small on large and huge setting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1817389/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
