Gamepad Left analog will also move camera (wrong)

Problem

When I'm playing with gamepad and pushing left analog stick to move character in game, the camera will also rotate (wrong). It is so annoying and impossible to play!

Solution

This might be due to Steam's gamepad-desktop control. You can disable this from Steam setting menu. Find the community preset named "Disabled".

Or better if you did not use Steam Big Picture or anything fancy, you can totally disable these gamepad extra function Steam is giving by going to similar menu, uncheck all the support.
