When I start game, pick my char, enter game and alt+tab , my browser is like on 1/4 size of screen. To get browser to full size, i need minimalise and get to full screen
Game resolution is 1920*1080 fullscreen on 17´´ monitor, graphic card Radeon R9 280x. Running on win 7 64b and windows screen resolution is 1920*1080 with active aero.
I guess It probably have any relation with loading screen or choose menu character resolution.
Anyone else have same problem or knows solution,plz?
Oh and i forgot, I use Google Chrome browser, and i am not sure but same thing happens when i use IE browser.

same problem with Firefox

my solution: playing in window mode :X
