Description slartibart70 2016-07-12 21:11:21 UTC
I did an update to kde frameworks 5.24 of fedora testing repos.
Reboot system, then login to kde.
- Systemtray seemed to be missing (no icons)
- i unlocked widgets
- systemtray was still there, but empty. Toggling systray entries (like battery of software updates) did not restore the icons
- i removed the systray completely and re-added it
- Icons reappeared, but kde was complaining about not being able to show laptop battery indicator (i also got some errors in .xsession-errors, e.g.
file:///usr/share/plasma/plasmoids/org.kde.plasma.battery/contents/ui/batterymonitor.qml: QML Plasmoid: Cannot anchor to an item that isn't a parent or sibling.)

- logout and login to kde
- systray gone missing again
- same procedure as above, remove systray and re-add it
- now, battery icon is available und works properly

- new logout and re-login: systray gone missing again... :-(


Reproducible: Always

What Qt version are you now on?
Comment 2 Colin J Thomson 2016-07-13 19:05:15 UTC
I am also seeing this and using Fedora 24, Qt version is 5.6.1
Comment 3 Jacek Pawlyta 2016-07-14 12:01:11 UTC
I see exactly the same problem with system tray. 
Fedora 24
KDE Frameworks 5.24.0
Qt 5.6.1 (built against 5.6.1)
Comment 4 Rex Dieter 2016-07-14 12:19:29 UTC
I can confirm this (clearing needinfo as well).
Comment 5 Rex Dieter 2016-07-14 12:23:58 UTC
If it matters, when qt-5.6.1 landed, only selected pieces of plasma were rebuilt, those known to use (or potentially use?) private apis:
plasma-integration
(all other existing plasma builds are done against qt-5.6.0).

and all of kf5-5.24.0 was built against qt-5.6.1 too.

I mention this in case anyone knows of other plasma modules that should be rebulit on Qt5 upgrades (besides plasma-integration).
Comment 6 Rex Dieter 2016-07-14 12:33:57 UTC
I upgraded plasma-5.6.5 to plasma-5.7.1 (which was all built against qt5-5.6.1), and this issue seems gone.  So seems either to be something fixed in 5.7.1 (or some other explanation, like some other plasma module(s) needed rebuilding against qt5-5.6.1 too).
Comment 7 slartibart70 2016-07-14 18:10:57 UTC
just to add my config:
fedora23, qt 5.6.1

Kwin and kwayland; though i doubt this makes a difference for this issue.
In KF5 land, kdeclarative needs rebuilding (shouldn't, but as it can sometimes happen, reality is different, see https://bugreports.qt.io/browse/QTBUG-46433 and https://bugs.launchpad.net/bugs/1426335)
Comment 9 rооt 2016-07-15 06:25:18 UTC
Kubuntu 16.10
KDE Frameworks 5.24.0
Qt 5.6.1 (built against 5.6.1)

system tray working again if the widgets are not locked

No icons in system tray if widgets are locked

Reverting these 2 commits seems to fix the issue: 
1. https://quickgit.kde.org/?p=plasma-framework.git&a=commitdiff&h=6f5816fc575927201a1aa9cc1fdb0c75a1a3ab69

Comment 12 David Edmundson 2016-07-15 17:01:53 UTC
That second commit won't make a difference to anything
Comment 13 slartibart70 2016-07-18 19:33:55 UTC
retesting with KF5.24, qt5.6.1 and plasma 5.7.1 of fedora testing repos.
Seems to be fixed, no more need to have 'widgets unlocked' for functioning systray.
Thanks!
Comment 14 Pulfer 2016-07-19 02:51:29 UTC
IMHO, KF 5 updates shouldn't break older Plasma 5 releases. It shouldn't be a game "guess which version of KF properly works with which version of Plasma". This bug is marked fixed now, but in fact it still exists in Plasma 5.6 branch used with KF 5.24.
Comment 15 Andreas Sturmlechner 2016-07-24 18:37:45 UTC
Yes, this should definitely be fixed.

better bookeeping of the config

be able to destroy applets even when locked: delete their config
by hand.
Except in one case: when the applet gets automatically destroyed
by dbus activation do *not* clear the config, it should be
reused next time.

reuse existing applets config

When there is already a config for a given plasmoid, reuse it
instead of creating a brand new plasmoid (having config groups
endlessy accumulating in the config file)
