Windowed Mode

[Eriko123Yo]

I play on windowed mode as the fullscreen BREAKS MY EYES and it also reduces lag on my potato pc, however in the last few days my mouse keeps zoning in and out of the game, so if I turn there is a chance that I will just have to click back on the game again, it may not seem like a big issue but it has caused me some deaths and with the stress of every slight turn the mouse might zone out it is getting really annoying, is this a bug which will be fixed? Or does anyone have any solutions? Thanks :D

 

PS: It only happens with this game, I have tried restarting my computer and changing the mouse.
