Hello. I don't really know if this glitching happening only to me, but still might send it to you. 

So I have a not great laptop but still is usable and can play minecraft, but for some reason if I start minecraft with snapshots or pre release verions it gets all buggy and glitchy, screen and text is bugging, lagging.  

I think maybe this is happening to me only cause maybe my laptop cant handle the new versions. 

If you cant find a problem its okay. Thank you !
