Left trigger on xbox contoller adjusting the size of pc link window while playing a PC game

Does anyone out there have a solution to disable the window screen adjustment function of the left trigger. In the middle of the game I'll press the left trigger to aim on COD. It aims down the sight, but once I move the joystick it adjusts and modifies the screen. Ive researched with AI and haven't had any luck to solution. Thanks in advance for any guidance.
