I am actually having the same issue. It began when I updated to 1.0. Never had an issue until the update. I've tried reverifying the files, reinstalling, uninstalling all mods, etc,. I ended up getting it to be resolved by changing a start up setting and messing with the options when I was in a newly created colony.
First I set the launch option of: -popupwindow
After that I created a random colony and was able to access my options menu. I don't know if this has anything to do with it, but I noticed the resolution was not set to 1920 x 1080, so I set it to that. Maybe the game is trying to resize and adjust itself while in the options menu? Either way this resolved the issue for me.
