ebutler, thanks for the workaround, I will try it.

In the meantime I tested at least the live version of the latest development version of ubuntu
(trusty-desktop-amd64.iso 09-Jan-2014 07:51 910M)
and found the same bug also there.

I am going to update the report according to what I was asked above.
However, I think I will not try the latest kernel at the moment. I think that if the bug is really in xorg, then using a different kernel would not help. (If I am wrong please notify me and if really needed I will install the development version of ubuntu on the hard drive and will test also the kernel.)
