impress Slideshow corrupts in 4K screen

Hi I am using Impress Version: (x64) I tried the newer version as well. It worked for a while, but now even with a new sideshow with just a couple of slides which are automatically generated, it seems as though there are four slides on the screen when the slide show is run, though I can only see the edges. I was wondering if there is a problem with 4K screen resolution as that is the only reason I can guess for 4 slides.
Thanks for you help.
