When Im modeling anything in Maya 2015:
Hello. If this is still a problem, I would uninstall the software and delete the residual Maya folders from these places:
C:\Program Files\Autodesk\
C:\ProgramData\Autodesk\
C:\Users\All Users\
C:\Users\**YOUR USERID**\AppData\Roaming\Autodesk\
C:\Users\**YOUR USERID**\AppData\Local\Autodesk\
Now reinstall and update your graphics card drivers and test.
