I use lakka the last version and I have problems when I take the list is too long with the Thumbails become black and collapses the system goes crazy or breaks. But if I enter a game and I leave this it normalizes. Some solution or the best will be to disable the thumbnails.
I find if playlist too long,some ROM can’t run,even before it can.
The roms run I do not have problem with that, the problem is that the photos of the covers disappear and turn to black producing errors the lists disappearing the same. Also disappear when I see any list in a fast or continuous way this is like random. So if I play any rom this is fixed and the thumbnails look good just like the graphic disappearing from the lists.
Here is the link on youtube with the same bug without using dynamic wallpaper
The bug is the same, the problem is that you do not see any solution. And it is to navigate fast that happens and can not load all the photos so the whole interface is dropped
