Comment 3 for bug 2056657

In autostart, I have exactly one file - Telegram, installed from https://flathub.org/apps/org.telegram.desktop:

$ cat ~/.config/autostart/org.telegram.desktop.desktop
[Desktop Entry]
Type=Application
Name=org.telegram.desktop
Exec=flatpak run --command=telegram-desktop org.telegram.desktop -autostart
X-Flatpak=org.telegram.desktop

~/.local/share/applications has one .desktop file without Icon= in it, honestly I am not sure where did it even come from:

$ cat ~/.local/share/applications/userapp-Firefox-YMM3I2.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
NoDisplay=true
Exec=/usr/lib/firefox/firefox-bin %u
Name=Firefox
Comment=Custom definition for Firefox
