frozen YaST2 Qt interface

After one of the recent TW updates (cannot tell the exact version), a few Qt based applications stopped working over SSH X forwarding. Tested with Qt Creator, a custom built Qt application (OO Mapper) and YaST2. At the same time some other X based applications work fine - xterm, xmessage, git gui, gitk.

Example replication procedure (from the attached picture):
lpechacek@fm:~> ssh -X -l user germ146.suse.cz

Have a lot of fun...
user@germ146:~> /usr/sbin/yast2 --qt
 # ... window appears but remains black
 # strace shows events are delivered to the application

With TW 20180530 these Qt applications worked fine.

According to https://lists.opensuse.org/opensuse-factory/2018-06/msg00076.html KDE apps are affected too and the issue first appeared with TW 20180606.

A fix has been submitted a week ago already, but is still stuck in staging...
