Mattermost app's icon - svg file
SUMMARY
I'm running OpenSUSE Tumbleweed with Plasma 6/Wayland and at some point a while
back I noticed that the svg icon of a Mattermost app installed via flatpak
started to render incorrectly: for some reason the white part of the icon in
the middle doesn't render properly. I thought that it might be an issue with
Qt6 svg rasterizer but a prototype PyQt6 app demonstrating the icon in a widget
renders this particular icon correctly so the issue must be somewhere on the
Plasma 6 side.
STEPS TO REPRODUCE
1. Install Mattermost app via flatpak (com.mattermost.Desktop, version 5.8.1)
2. Add Mattermost app icon to a panel or just observe the app's svg icon via
Dolphin in folder
/var/lib/flatpak/app/com.mattermost.Desktop/current/active/files/share/icons/hicolor/scalable/apps/com.mattermost.Desktop.svg
OBSERVED RESULT
The app's icon is not rendered correctly - the white curvy part in the middle
is seemingly rendered in wrong color.
EXPECTED RESULT
The app's icon is rendered correctly
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: OpenSUSE Tumbleweed 20240613, Wayland session
(available in About System)
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1
ADDITIONAL INFORMATION
The app's icon is properly rendered in Inkscape and in the following PyQt6
prototype app:
from PyQt6.QtGui import QPixmap
from PyQt6.QtWidgets import QApplication, QMessageBox, QLabel
app = QApplication([])
msg = QMessageBox()
pixmap =
QPixmap("/var/lib/flatpak/app/com.mattermost.Desktop/current/active/files/share/icons/hicolor/scalable/apps/com.mattermost.Desktop.svg")
label = QLabel()
label.setPixmap(pixmap)
msg.layout().addWidget(label)
msg.exec()
