Comment 16 for bug 1909622

Until the associated upstream bug is fixed (which is ultimately a problem with the XDG implementation in LXQt), this should continue to happen in all releases, Focal and otherwise. We DO have the right setting in the Desktop Entry, so once it is fixed upstream, packaged, and released in Ubuntu, everything will Just Work™.

That said, I wouldn't necessarily discourage reporting of this issue on the ISO tracker (so we don't forget about it), but I wouldn't bother with any more extensive testing or troubleshooting.

The release notes should cover us for those people that don't just select the icon on the desktop or pick the Lubuntu-specific option from the menu.
