Disabling the fallback to XRender. It's causing more trouble than the benefits.

Browse source 
With Intel drivers currently the self check at KWin startup fails (no idea why) and KWin falls back to XRender. This is probably an explanation for all the complaints about slow kwin in 4.5 and the missing effects. So let's fail and make it possible to restart compositing via systemsettings and alt+shift+f12.
Nevertheless it would be nice to fix the the failing selfcheck...
