sometimes my game gets weird and dark here are some images as an example. i have no idea why this happens and it is very rare that this happens.

that's so weird! I've never seen anything like that before.

I had something like that on a very old PC that had a poor graphic card

I also play on a very old laptop (windows seven to be specific) but it has windows 10 installed on it

Could be caused when changing the window (with alt-tabbing or pressing the windows key etc.)

Guess this happens when playing on a gfx card older than the game itself? Not sure as I've only now seen this glitch.

Update: Someone else also had this happen to them.
