I don't use Fedora, but do you know if your kernel or GPU drivers have been updated to a newer version? If so, there could be some kind of bug causing it, and you could try downgrading your packages. I would also check to make sure the refresh rate on your monitor matches your OS. The Steam logs would also be a good place to start, if you haven't checked them yet.
