Hello,
This definitely sounds like a video card (or rather driver) issue.
First go to Window > Preferences > OpenGL settings and disable (uncheck) Hardware accelertion. If it seems to fix the problem, don't be happy yet as if you work with HW acceleration off, SU may become slower with bigger models as well as some plugins (like LightUp for instance) won't work.
You will need to make sure to update your video driver. Hopefully you don't have an "integrated video chipset" in your laptop - as they don't seem to fully support OpenGL - but unfortunately many "mediocre" laptop builds come with them nowadays (typically Intel motherboards tend to have these...).
