Comment 6 for bug 1455711

This is not so much a KDE Plasma 5 issue, but more an issue of legacy applications still not supporting a reasonable systray protocol (SNI).
There are workarounds like [sni-qt](https://launchpad.net/sni-qt), but this won't help with crippled/statically linked applications like Skype.

For more details on what's going on here, see this blog post by KDE's kwin developer Martin Gräßlin: http://blog.martin-graesslin.com/blog/2014/06/where-are-my-systray-icons/

I'm undecided whether distributions should really put effort in workarounds for legacy apps or instead should put pressure on the upstream of those projects to finally adopt SNI.
- In one case, the user experience might suffer when a user expects an application to continue to work as "it always did"
- In the other case, it keeps the whole ecosystem from finally adopting modern best practices and communicates to upstream projects "it's fine to use outdated technologies".
