I realize this is not a bug in Plasma 5, but I don't know of a better place to file this report. qt-recordMyDesktop minimizes to a systray icon so recording can be stopped. This works in KDE4, but in Plasma 5 no systray icon appears, and the only way to stop recording is to kill the process - the written video and audio streams are then unusable. This is probably not only an issue with qt-recordMyDesktop but with all apps which use the old systray plug. What are users of Plasma 5 to do? Is there a workaround, or is the only option to wait for a Plasma 5 version of these apps to be released? Reproducible: Always
We dropped support for the super legacy X system tray protocol and only support the AppIndicator/StatusNotifierItem protocol For any Qt5 app this will happen automatically, all KDE4 apps used this directly, and there are modules for GTK. Plain Qt4 is missing, unless that app adds support themselves. See http://blog.martin-graesslin.com/blog/2014/06/where-are-my-systray-icons/
The GTK version seems to have support: http://www.webupd8.org/2010/09/install-gtk-recordmydesktop-with.html
I tried media-video/gtk-recordmydesktop-0.3.8-r3 and media-video/qt-recordmydesktop-0.3.8-r2 and neither showed a systray button.
FYI: KUbuntu 16.04.1, gtk-recordmydesktop 0.3.8-4.1ubuntu1 — systray button exists, but has no icon; i.e. looks like a gap between other systray buttons (Keyboard Layout and Audio Volume), so not easy to guess that it belongs to recordmydesktop.
