I am using OpenSUSE Tumbleweed oracle JDK 1.8.0_65 (64bit) with netbeans 8.1. It works with previous plasma 5.0.x Reproducible: Always Steps to Reproduce: 1. Open Netbeans 8.1 2. Copy some text to clipboard in editor 3. after 2nd selection plasmashell freeze
It doesn't happend everytime and you have to use java editor.
xsel -bc unfreeze plasmashell for few seconds
I can see in sysout repeating line: QXcbClipboard::setMimeData: Cannot set X11 selection owner QXcbClipboard::setMimeData: Cannot set X11 selection owner
There is no freeze after upgrade to plasmashell 5.5.2
