I am having a really hard time ever since I moved to KDE from Gnome. I honestly don't know where to start with troubleshooting. I am on an Intel NUC running intel graphics. All third party software runs just fine (Chrome, Libre Office, ...) but all system windows including Settings and Konsole just simply won't render at all as you can see in the screen shot. I know it's really bad form to not post logs with screenshots, but i'm honestly not sure what pid to gdb. As is I'll have to move back to Gnome, which would be awful because Plasma is so amazing. I've been running KDE Neon on my laptop for a while with no issues. On my NUC I'm using the DisplayLink driver to connect an additional 2 monitors to my rig (3 in total) and that's the only thing I can think of that would be causing the problem. I don't have any issues before I install the driver but after I uninstall the drive the issues don't go away.

Forgive me. My images were too large and I bundled them into a Google Photos album. https://goo.gl/photos/hisxtTUcpxufgv3D9

******UPDATE*******
I was able to figure out the issue is related to Displaylink. i uninstalled again and rebooted and this time the issues went away. I'm guessing I pull the DisplayLink logs? Would you care to see them?
