Hi,
I redid my library on my Vero 4K because I was bored not having the covers.
But now, it’s like unusable… I mean, it’s lagging hard, covers take like 2 minutes to show up, I often have the 
smiley but for some reasons the CPU doesn’t seem to be at 100%…
I wonder: is it because of TMDB scrapping or is it because I have exactly 18786 video files scrapped from my NAS and then the Vero4k can’t handle such amount of files? 
When you first scrape a library it can take a while before all the images cache and the lag goes away.
Have a look at this
Yeah it looks like that actually. And sometimes it’s showing up after like 2-3 minutes or sometimes I just have the smiley.
I also use the wall view. I also noticed now, if you jump during the video, the video freezes for few seconds.
It might be the last update. 
Is only Estuary affected?
Hm yes… It seems like only Estuary is affected. I tried with OSMC skin and it seems ok with this skin.
I tried with some other skins and I can confirm only Estuary is affected. (Sadly I like Estuary…)
We are working on it. Estuary is maintained upstream by Team Kodi but we are trying to figure out what is going on to inform them.
But maybe it isn’t a skin issue but just exposed by more views in that skin.
Oh ok, then it was a coincidence, I simply decided to scrap my collection at the wrong time 
I also tried FENtastic skin which is similar to Estuary and it’s fine with FENtastic.
I didn’t understand how to have movies and shows on main page even by reading the guide. (But this is another question)
Thank you for the explanations!
