At least all building buttons; do not remember about menu ones.
So it not possible to build anything in fullscreen.
I have 1920x1200 resolution, if it helps.
I've added all the details to our post-launch bug list
We will be updating the game next week
I hope it wasn't a game-breaking bug for you
I tried to replicate the bug you've reported but couldn't. I've used very similar resolution but everything seem to work
Tried different browsers but it made no difference
Would like to fix it but not sure how if I can't reproduce it :(
