MATLAB: Colorbar error – how to fix it

colorbarerror

I am currently experiencing problems with the matlab colorbar. In the beginning i thought it was an error with my script, but now i am convinced it is an error with matlab since even the most basic uses yields this error. It must be something interacting with matlab, because the error is unique to this machine and didnt always occur on this machine. I have tried uninstalling and installing the same version of matlab and even a never version to be sure, with no luck.
The error presents itself as many numbers being printed on the colorbar instead of what is expected. For example:
surf(peaks(30))
Gives this figure:
however when i click the colorbar button or use the command
colorbar
I get this figure:
It is very weird to me since it is so basic (i only need two commands to make this error). It should be noted if i try to save the figure as an image it will save the right figure, but with no colorbar or numbers. That is why i took the screenshot for the second figure. Anyone have any idea as to what might be causing this? I am at the point now where i am seriously considering reformatting my computer because of this, but it would be nice to at least have an idea as to what could be causing this, to make sure it doesnt just happen again in the future.
Kind regards, Mikkel Gram

This could be cause by the OpenGL driver. Did you install the newest drivers of your graphics cards?
Workaround might be:
set(gcf, 'renderer', 'zbuffer');
or if OpenGL looks nicer:
opengl software
or perhaps:
opengl hardware
Look for "OpenGL" in the documentation to find a bunch of switches to consider a bunch of driver bugs.
