I finished downloading/installing Dota 2 recently. When I go to run the game, the resolution first changes to 1080x720, then there is white grid lines everywhere. The grid lines themselves go above the mouse cursor and when I went to take a screen shot of this, the picture had no grid lines on it.
I attempted changing the resolution within the game but I'm unable to read a thing, so I wasn't able to reach the settings.
Any help to solve this issue is appreciated!
