bug#13106: Graphical glitches in Cocoa Emacs

[Bjarte Johansen]

Hi,
I have some graphical problems in my emacs installation. 

I will most of the time In Cocoa Emacs see graphical glitches on the text and 
other places in the window. Usually it manifests by turning a pixel or two a 
different colour then what it is supposed to be. Sometimes there will be a 
line, It is usually in areas of high change. I have a clock on the right side 
of the mode line. After some time some of the pixels around the characters will 
turn green. It is most often (if not all the time) on the right side of the 
screen, as if there is a "off-by-one"-error. 

Other times I will also see a darker colour next to the right fringe. This 
colour is the same as the colour I have for the mode line and cursor. 

In the package list there will be some small areas on top of the buffer that 
does not change to the darker colour I have set it should have and will keep 
the background colour. 

The version I have been using is Emacs 24.2, but I have had this problem since 
Emacs 23.* (or when started using OS X).

Thank you for your time.

Regards,
Bjarte Johansen
