I don't use Fedora, but I do have a Debian installation I like to keep current on a spare drive as a backup OS and to keep current with the Apt world. I have never had any issues like this between these two distros.
"For some reason in Fedora 42 the Konsole is higher" I am not sure what you mean by this exactly.
Have you thought about backing up any existing config files on the Fedora installation and replacing them with the Gentoo versions? In general, depending on the program and distro customizations, this has been enough for me to get the preferred behavior.
The other thing to consider is whether you are using the same type of Plasma session, i.e. Wayland vs X. Also verify that you are using the exact same desktop resolution and that scaling is the same. You can even turn scaling off to compare the performance. Also you might try using the exact same font. You can install fonts locally or system wide using KDE System Settings. You can also just copy the fonts from Fedora to Gentoo, or vice versa, but you may need to regenerate the font cache or delete the files in cache (more about that at the end). Just make good backups of your existing files in case you have any unexpected issues. System wide fonts are usually stored in /usr/share/fonts and locally (I think) in ~/.local/share/fonts.
You could also take the time to compare any relevant config files rather than just copying them over as a test.
I found these in my home directory:
Code: Select all
~/.local/share/kglobalaccel/org.kde.konsole.desktop
~/.local/share/konsole/Profile 1.profile
~/.local/share/konsole/bookmarks.xml
~/.local/share/konsole/bookmarks.xml.tbcache
~/.local/share/kxmlgui5/konsole
~/.local/share/kxmlgui5/konsole/konsoleui.rc
~/.local/share/kxmlgui5/konsole/partui.rc
~/.local/share/kxmlgui5/konsole/sessionui.rc
~/.local/share/plasma_icons/org.kde.konsole (1).desktop
~/.local/state/konsolestaterc
This is not likely to any difference but you might also as a last resort delete the files in the cache (~/.cache/*) while logged out (from a tty) and then login again to let the files newly regenerate. I have found Plasma tends to lean into the cache when settings are changed, usually fonts and images, and does not always update configuration changes but loads whatever is in cache instead. SDDM, for example, is guilty of this with regards to themes, fonts and background images that are manually copied or changed outside of System Settings.
