xf86-video-intel broken since 2.99.917+xxx?

In newer driver versions (seen from 1:2.99.917+364+gb24e758-1 onward under KDE) parts of the desktop freeze and don't become redrawn. After changing window focus or minimizing/maximizing the window is responsive again (with some luck).
This effect has been watched on different newer and older intel graphics chips.

Switching back to UXA acceleration seems to resolve the problem.
/etc/X11/xorg.conf.d/20-display-intel.conf:

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option      "AccelMethod" "uxa"
Endsection
