Interface lag with a big playlist

[Yuu]

-Sorry for my bad english-

Since a couple of days, I'm creating a playlist with all the songs I want to hear and since yesterday, my vlc interface starts lagging a lot ! I think it's because of the size of the playlist, however there isn't so much songs I use to have in a playlist... and it's very annoying when I want to scroll the playlist in vlc. But I don't have any audio issue. Is there something I can do about it ? Thanks in advance.

Edit : I realized the lag comes only in "Icons view"
