i recently updated to the latest beta and noticed in the change logs:
Added a new option for disabling "sticky corners" in Windows 10
i personally quite like this feature of windows 10 and would find it quite useful to have in windows 7. currently i have my 2 monitors set in the display settings to be offset by about 10mm when the physical monitors are actually level. this works but gets on my nerves when i have windows spanning both screens. as such i would really love for an option that enables this feature in windows 7.
This is currently on our feature request list, so I've added your vote to it. We'll be sure to let you know if/when we're able to implement it in the future.
