Hello, i installed windows 10 today and found some issues running it on the 5k iMac. The first issue is a image bleed effect i guess you could call it, the imahes like wallpapers are bleeding and images does look as smoth (sorry cant really describe this well will post screens shots latter on) also when opending the start menu thr images bleed even more This bug can be fix by changing the screen size lower but does this brings other problems. The next problem when going to desplay setting and try to change the screen size not all options are there 3 sizes 3840 x 2160, 2k screen size and something around 720p screen size (unlike on window 7 where it has a bunch more) also in 3840 x 2160 plugging a second monitor in will not pick it up and the second monitor will be blank changing to 2k will fix the issue. Changing the screen to 2k fixes the image bleed but bring another issue all text is destroyed and broken but if a second monitor is on the text on that screen will be fixed but broken on the 5k iMac. I dont know if this is something I can fix on my end or if its on Microsoft ends or apples end due to no window 10 bootcamp drivers that im a were of. Thats about it for bugs that I've found so far (tho have not been using it for long) Thank you for your time and I hope you all have a great day.
