15' MBP 2016's native screen resolution is 2880x1800 but in Parallel the maximum screen resolution is 3360x2100. This bug leads to an blurry screen of my Windows XP virtual machine no matter how I adjust the display settings. IMO, parallel can just map 1 pixel to 4 pixels and show a sharp and clean 1440x900 screen on 2880x1800 HiDPI screen.
