Short description of error
I have a .blend file with 24 objects, half of them have the "hide_render" property animated (to make them appear at a certain keyframe), which is also driving the "hide_viewport" property in order to better see the sequence on the viewport. Some object, which was supposed to appear on frame 1972, appeared for no reason on frame 1239, for just one frame. This object's visibility was driven by another object, but the other object did not misbehave. I rendered the single frame 1239 afterwards and there was no visibility problem.
Exact steps for others to reproduce the error
I am unable to reproduce the problem, since rendering again doesn't trigger it. The current visibility system paired with keyframes and drivers seems to trigger it.
