windowed bug leads to windows beep

bug report ID：#683559434

this seems to goes after the previous bug that occurred to me :https://www.pathofexile.com/forum/view-thread/3822274

reason i will not use windowed mode--- keys' action is not fully seperated with as in windows: when alt is hit down and you use whatever hotkey on keyboard (such as WASD)it runs but also windows will beep to remind a wrong hit in desktop. thats annoying
