I have seen this, but not at startup. This issue could be related to the OpenGL renderer in MATLAB. It is recommended to update the graphics card drivers.

You can also try to set the default renderer to "painters". Copy the below line to your "startup.m" file.

set(0,'DefaultFigureRenderer','Painters')

For more information on the "startup.m" file, refer the dcoumentation page for "startup.m" file below.
