Having the same problem for about a week (?) or so, it happens almost every game and in some games even 3 or 4 times. Sometimes it happens twice in a row in the same minute, sometimes it only happens at the very end when the nexus is about to explode.
I've tried closing all other applications while playing, disabling all non-Microsoft related background apps, tried pressing the mouse 4 button, updated graphics drivers, disabling the Office background task handler registration/logon thingy that has been suggested a lot, disabled antivirus and firewalls, made the League Client close while in game, and made a custom game where I click literally everywhere on the screen to see if it has effect.
Nothing works, I'm losing games because of it since it takes me about 5 seconds to re-focus the game. Last option, playing borderless or windowed, but those make camera- and mousemovements feel very stuttery for me and cuts my fps in half. Not gud, Rito ples T-T
I tried all this also before coming here! Even uninstalled recent windows updates. I tried the hextech repair tool also and forced repatch.
The last thing ive tried is a full restore which i havent had a chance to test yet.... also 10.5 came out today, fingers crossed.
99.99% sure its a League problem though and not a windows thing, all other games are still working fine, no tabbing out of cod, apex etc...
