Sure . There is an example :
Well it's not normal.I mean it kindof is if you dont have 16:9 monitor ,but i think that there's kind of fix for it.Because my old Benq which was 16:9 I could've see the whole item I guess.
I think he means the item was striped or such. Can I have a screenshot, more information (description of this phenomenon, does it always happen, only some items etc.) and perhaps your specs (not just the monitor). A dxdiag would be nice too. Welcome to the forums by the way, I hope you like it here. A tip: try being more precise, posting screenshots is great (if you wish, just upload it to dropbox or imgur and give us the link :D). Have a great day!
My specs are : 1tbhard disk seagate , hd 6450,6gbddr31666mhz,some old i3 i don't know the exact model.I don't think its due to specs because I get solid 140 fps on 12+render distance,fancy settings w/o optifine.
