not compatible with dual display with different dpi scaling

I launched virtualbox in display 1 with 200% dpi scaling, when I drag the window to second screen with 100% dpi scaling the title of the window become very large. instead, when drag from 100% to 200% every thing in 200% become very small.

在Windows上，如果主屏幕设置成125%，讲第二屏幕设置成100%，那么如果讲虚拟主机拖到display 2上显示的话。鼠标就成虚的了，并且还有一个乱码显示。 如果两个屏幕都是100%就不会出现这个问题。
