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!

Try updating your the driver of your GPU.

Anyway this is how the options should look

The options button is the cog at the top left of the screen.

@mr_skeleton: Thanks! I didn't "remove" the lines, but I was able to navigate to the settings and change it to 1920x1080. Which got rid of the lines.

something like a phenomenon
