Fix LibreOffice Flatpak Wayland Icons on KDE
LibreOffice uses the generic ugly Wayland icon on KDE when installed from Flathub. It's a known issue without a reliable workaround, even using KDE's "window rules".
Well, I finally found the window rules needed to force the correct icons. It's pretty hacky, but at least it works.
Follow this guide or paste my rules at the bottom to a .kwinrule file and import it.
The trick is that each LibreOffice app needs two window rules, described below. I'm still not exactly sure why, but it seems like LibreOffice changes its "Window Class" -- which KDE uses to match the window -- between two states, each of which need a rule.
Let's start with LibreOffice Writer. Add a rule like below:
- Window class (application): [Exact match]
libreoffice-writer - Match whole window class: No
- Window types: All
- Desktop file name: [Force]
org.libreoffice.LibreOffice.writer
And then the other one (this took me forever to figure out):
- Window class (application): [Exact match]
soffice - Match whole window class: No
- Window types: All
- Window title: [Regular expression]
Writer$ - Desktop file name: [Force]
org.libreoffice.LibreOffice.writer
This rule is because sometimes LibreOffice uses soffice as the window class, which makes it harder for it to determine which icon to use. The regular expression determines this by using the window title, which happens to always end with the name of the LibreOffice app AFAICT.
Repeat this rule creation pattern for each app. You can use the table below to reference the important details. There will be 14 rules at the end. Wow.
| App | Rule 1. Window Class | Rule 2. soffice Title Regex |
Desktop file name |
|---|---|---|---|
| Writer | libreoffice-writer |
Writer$ |
org.libreoffice.LibreOffice.writer |
| Calc | libreoffice-calc |
Calc$ |
org.libreoffice.LibreOffice.calc |
| Impress | libreoffice-impress |
Impress$ |
org.libreoffice.LibreOffice.impress |
| Draw | libreoffice-draw |
Draw$ |
org.libreoffice.LibreOffice.draw |
| Base | libreoffice-base |
Base$ |
org.libreoffice.LibreOffice.base |
| Math | libreoffice-math |
Math$ |
org.libreoffice.LibreOffice.math |
| Generic | libreoffice (Substring match) |
n/a | org.libreoffice.LibreOffice |
The last Generic rule must be placed below the other rules. It will ensure any other LibreOffice windows, such as the splash screen and the home page, use the basic LibreOffice window.
It may be ridiculous to have 14 rules to fix the icons of a single program, but just think of the productivity gained. You can know at a glance exactly what a window is, instead of flipping your desk at the sight of a Wayland icon, sobbing about why such a basic seeming issue hasn't been fixed yet. Or maybe that's just me.
To save time, paste the following content into a .kwinrule file and import it from the Window Rules settings page. Make sure to drag the "catch-all" rules below the others after importing.
