These/similar spamming log message have been reported for years, with everybody pointing at someone else

Finally, the last link suggests patches were made available for Fedora

, i.e., at the distro.

That's just a downstream bug which links to an upstream bugreport which I've already been tracking. It doesn't look like upstream is interested, for some reason. The real source is https://bugreports.qt.io/browse/QTBUG-55167 (which you linked already).

Here, on Opensuse, with

rpm -q --whatprovides /usr/bin/plasmashell plasma5-workspace-5.14.3-lp150.429.1.x86_64

(from, http://download.opensuse.org/repositories/KDE:/Frameworks5/openSUSE_Leap_15. 0)

this cat /etc/xdg/QtProject/qtlogging.ini [Rules] qt.qpa.xcb.xcberror=false

has no effect on these messages.

That has nothing to do with plasma, that's a Qt configuration option. The patch isn't a real fix either, it just makes it possible to hide the messages. IMO the messages are actually useful and shouldn't be hidden by default as they're actual errors. The patch is harmless though and can be submitted to 15.0 - so reassigning to SLE Qt maintainers. -- You are receiving this mail because: You are on the CC list for the bug.
