strange delays

[Avezo]

For past few days I'm having weird issues with Factorio (and only it). Sometimes when I press any key or mouse button it doesn't work immediately - it may take even few seconds for game to realise I did something. There are no lags, just these input delays, like playing on server with high ping (but I play 100% singleplayer). Same with stopping pressing it - say if I started to walk in one direction, then take my finger off the key - character would still keep walking for few more seconds. It happens even in menu window, I've tried to load a game, had to wait few seconds before it was lighted after clicking it.

I don't really think it's a problem with Factorio itself, but more my laptop, because it started after taking it for a relatively long trip in a car without AC (still only around 30-40 oC). But maybe not. If it matters, I've increased multisampling from default seting, but I don't remember how anymore lol.
