I have been suffering similar symptoms[1] on a AMD Kaveri APU powered box, 
running plasma with two monitors, which worsened[2] in the last couple of 
weeks.  All other boxen work fine, so I assumed some Radeon driver issue 
specific to this machine.

[1]  For some months now the RH monitor would not acquire the correct 
resolution.  The workaround I came up with, until I have some time to 
troubleshoot it, was to go into SystemSettings/Display, disable the RH monitor 
and then re-enable it.  This process is more painful than it sounds, because 
clicking on Plasma desktop GUI menus does not update the screen.  I have to 
drop into a console and back to Alt+F7 before I can see the output of whatever 
I had clicked on.  Interestingly, Plasma-Wayland worked fine, both monitors 
came up with the correct resolution.

[2] Last week's update broke both xorg and wayland.  Plasma crashes when 
launched and partially recovers.  I glanced at the errors and it seems to be 
related to some Qt library.  Again, I haven't troubleshooted it further.

Not sure if this helps, but would be interested to try in whatever fix you may 
come up with.
