#1 - still flickering, but it is far better, than default settings ;-)
In KDE go to System Settings > Desktop Effects > Advanced
When using compositing type OpenGL change Tearing Prevention (VSync) to "Full scene repaints" and Apply.
#2 - *recommended* as it does not flicker totally :)
In KDE go to System Settings > Desktop Effects > Advanced
Change Compositing type to "XRender" and Apply.

My HW configuration:
2x Radeon HD 3470 and 3 monitors - now with workaround #2 it works like charm
