If your game opens tiny (800×600 or smaller) bugfix

If your game opens tiny in the corner of your screen (800×600 bug): Log in to the game like normal. Once it loads up, and is tiny or in the corner of your screen, press ALT+ENTER or ALT+ENTER+ENTER. You will then be able to change the resolution of the game to be your proper resolution.

Older video so it shows a different now-fixed bug at the beginning:
