Hello,

I've noticed this the last two days and I'm not sure if it's a bug or I am somehow accidentally hitting a hotkey combination. When I have played Dota 2, I play it in Borderless Window mode on my center monitor. Somehow, out of nowhere, it just moves over to my right monitor, and of course now I can only see the upper left quadrant of the game. I looked at DisplayFusion options and saw Win+Alt+X would do that, and I just disabled the key combinations. After I did that...it still happened. Is there something else I am missing here?

I did disable this and it did not fix it. However, I think I may have found a fix for it and wanted to put that here in case someone else runs into this problem in the future..

I actually watched the replay of one of the Dota 2 games where it happened and put it on player perspective, and seeing where the mouse cursor moved when I disconnected (I just killed the task in Task Manager when the problem happened). It was in the upper left corner of the screen. I looked more through the DisplayFusion settings and found "Enable window caption middle-clicking to move windows to the next monitor (hold shift for previous monitor)" under Window Management. I tried middle clicking my mouse in the top left corner of the screen in the game and I saw the game jump to the right monitor! I tried holding shift and middle click in the upper left corner, and it went back to the center monitor. I turned this option off and tested it and now it does not move. I do use middle click for a function in-game, so this is certainly the explanation. I guess Dota 2 (and likely many other Borderless Window games, if not all of them) have an invisible window caption in the upper left corner.

I haven't played a Dota 2 game since I did this fix, but I tested it last night and it seems to work now.

Thank you for your reply!
