When I had frosting on my 294 it showed up much more strongly in the middle of the FOV. It was most obvious on flats and showed up as a weird sort of tetris like crystalline pattern.

I baked the dessicant, but be aware that if you open it up and bake the tablets you would likely end up with dust bunnies, and you may also still see moisture effects for a while. It took a week or so after I backed the tablets for them to suck up the moisture in the chamber and stop it frosting.
