Just that it’s so dirty. New ones are clean (and the filter media below the metal screen is white)…
Sounds like you figured it out. Sorry, but the the filter is really a last resort for light, occasional use.

There are a number of dryer vents available and since I was adding 4" foam insulation for the roof at the time I cut a piece sized to fit the window with a 4" hole at the bottom to put the vent.
There are dozens of other threads with other ideas as well, just for the search.
