Hi everybody:

Problem: Resizing of windows is broken as it is impossible to grab a window border.

Broken version:
full xorg git master build, 5. Apr 16:26, xserver git 901fbfbbbd71c0d8208095...

Known good version:
full xorg git master build, 22. Mar 17:13, xserver git 4fb31e4824d46edc80bb49b ...

System:
openSuSE 13.1 with kernel 3.13.9 and 3.14.0, Xorg git builds, AOpen i915GMm-hfs motherboard with Pentium M Dothan cpu

Reproducibility: 100%

Is this a known problem?

If not: Bisecting required?

cu,
  Knut
