Description Janek Bevendorff 2015-12-16 15:57:48 UTC 
This bug randomly happens. When I change to font from Oxygen Sans to something else, it goes away, but comes back when I change the font back to Oxygen Sans. Not sure if it really has something to do with the font, though.

I attached an image that shows how it looks.

Reproducible: Always

Previous bug #355677 was closed as RESOLVED WORKSFORME.
I had the same issue sporadically appear for months with gnome-shell on X11. There are several bug reports in Fedora's bugzilla for it:
https://bugzilla.redhat.com/show_bug.cgi?id=742776 , especially attachment https://bugzilla.redhat.com/show_bug.cgi?id=742776#attach_550877 .
This issue has gone for me, but I don't know why. Maybe an update in some font rendering library. You could try changing your hinting settings, that sometimes helped.

Also have a look at bug #356680, with upstream bugs https://bugreports.qt.io/browse/QTBUG-42386 and https://bugreports.qt.io/browse/QTBUG-36976

This also happens to me, but usually in the Menu as opposed to anywhere else. This is on the latest Nvidia drivers.

Still present in Plasma 5.8.4.
The kickoff plasmoid shows the same rendering errors as in attachment 97925 [details], while the kicker plasmoid is fine.
