Even if it's very common hardware, display artefacts are almost certainly 
the driver's fault. We've seen horrible regressions in the intel driver on 
F22, the worst one was crashing Plasma altogether:

At least that one is fixed now, but the rendering problems are a different 
issue, so the rendering is probably still messed up.

But your complaints are all valid, and even the display artefacts on common 
hardware with a driver shipped in Fedora are really not acceptable, no 
matter what component is to blame.

Sadly, we KDE maintainers can do little about screwed up drivers. Plasma 5 
now uses OpenGL (which, IMHO, is by itself a horrible decision! That one is 
to blame mostly on the Qt project, which decided to require OpenGL 2 for QML 
2), so it depends much more on the drivers than Plasma 4 did (and even 
Plasma 4 was affected by many driver issues at the beginning).
