Due to a major performance issue when playing videos in Firefox on Kubuntu, I use YouTube in a separate Firefox profile. I set a different icon for the desktop file using Dolphin (using the YouTube SVG from Wikipedia), however now when I click to open it the icon goes blank while loading but comes back after. I also notice the icon doesn't get lighter when hovered like the stock icons do.



The desktop file:

Code: Select all

[Desktop Entry]
Actions=
Categories=GNOME;GTK;Network;WebBrowser;
Comment=Browse the World Wide Web
Exec=firefox %u -P yt --class firefox-youtube
GenericName=Web Browser
Icon=/home/matt/.local/share/applications/YouTube.svg
Keywords=Internet;WWW;Browser;Web;Explorer
MimeType=video/webm;text/html;image/png;image/jpeg;image/gif;application/xml;application/xml;application/xhtml+xml;application/x-xpinstall;application/rss+xml;application/rdf+xml;
Name=Firefox YouTube
Path=
StartupNotify=true
StartupWMClass=firefox-youtube
Terminal=false
TerminalOptions=

Is this a known bug, or something I'm doing wrong? Overall been loving KDE so far since moving from Windows. This is the first issue I haven't found a solution online for so far.
