when travelling on minecart I lose the graphics in that i can't see the walls in mine etc just a colour and if i can see track moving it looks transparent. I can hear the noise of the cart movig on track. ( I have a large mine) and sometimes after a while the grapics return only to disappear further on the cart journey. After stopping they eventually return. This was happening after the latest version of minecraft released as was fine in previous version

Since upgraging to latest version of windows today there are several bugs.
the icon picture in world i have saved is gone( was there yesterday before upgrading windows 10 this morning and when i play the world I am gettig random freezing. I can hear the noises of viillagers etc but can do nothing except close the game and restart.. I seem to be able to play for a couple of minutes before the freezes happens again.
I havent rebooted my laptop since it upgraded this morning and have had no problem with other programs like mail or you tube. Not tried any other games
