Short description of error
When linking objects from another file it used to be that the screen & camera icon are not able to be toggled. Now this is also the case for the eye icon, at least from the outliner. You can still select and hide the linked objects via the shortcuts like H and Shift + H to toggle the eye even though they are disabled to be toggled from the outliner.
