I suspect what you are experiencing is due to the characteristics of modern Wide display visual systems.
Basically your brain is expecting a three-dimensional image focused at infinity, but it's actually a two-dimensional image focused on the display optics just in front of you.
Your eye gets confused and doesn't know where to focus and this in some people induces nausea. This can be more pronounced when taxying as you tend to be looking (focusing) even closer.
