Kodi isengard playing in top left corner

[Judgeged]

Hi guys I'm a newbie so that you for the add, whilst I'm on here I had a video issue of my films, programmes etc playing in the top left corner of the screen, but the menus etc all looking perfectly normal............I've discovered a fix
Go Into setting, video (set the video menu to advanced), then you will see 3 different hardware accelerations all switched on, I switched all these off and my playback returned to normal without changing any other settings hope this helps guys
