Mr. RetroLust

Yep thats what I thought and why I asked (thanks!), I noticed a performance drop in 4K when using most views I have in my theme, the game view where the video is inside the cabinet is running without problems but the views with large video (and graphics overlaying the video) are causing problems (jerky scrolling so to speak), I havent tested other themes with large videos though but I think you are safe for the time being using themes/views with smaller video. Turning off all transitions in big box will give a good performance boost as does turning off fan art backgrounds in launchbox image priorities, also let launchbox finish cache your images and use the clean up media option for maximal performance.

Could be theme related, have you tried a different theme?

go to the data folder and delete the Settings.xml file, this will reset your launchbox settings.

I had this problem once, when I turned off the option to show amount of games in the left panel it didnt close anymore. I also unchecked using controllers btw
