Iv looked but i can’t find this bug reported.
When i use the system tray settings “entries” tab it breaks the tray, I don’t need to change anything just hit the OK button, after that I can’t click any of the default icons, the only menu i can get is the main list even if I’m clicking the volume or network etc icons, even on the main drop-down menu i can not click any of the icons. The only way to fix it is to restart plasma.
I have tested this on a VM with brand new download of today’s stable .ISO and its exactly the same which is why i would have thought there must be a report of this somewhere but i don’t know how to describe it into a search, although iv tried.
Its a little hard to explain so iv taken a screen recording. I show the tray working as normal for the first half then go to the settings and hit OK and then show how it affects the tray.
