I didn't encounter too many issues, in fact I only noticed one and it tends to disappear after I move about the screen a bit.

* When I have a my first capital ship built, I notice in the upper left side a bit of the planet icon next to the capital ship icon.  Sort of like when you have a webpage freeze and you open up another page you still see part of that old page.

Otherwise I can't wait to be able to play as another race beside the TEC (Personally I hate them)
