Note: I have this issue from before the introduction of episode art into the episode lists. It is not new, had it for ages, I just manage to write about it now
Basically, I can always reproduce it by first filtering the episodes from the initial screen (after initial start), then going back to the podcast list and opening the episodes of a specific podcast. The page always open with lags and freezes (sometimes only the downloaded episodes are shown first and the other ones come a few seconds later).
If I then go back to the podcast list and filter again, then the filtered episode list opens with lags an freezes.
Anyone else with this problem?
