Mouse limited to reduced area at higher resolutions / DPI

Issue found with Xonotic 0.8 on laptop which has a 3k screen (~210 dpi at 2880 x 1620, 15.6") running Windows 8.1.

When the resolution is set to anything above 1600x900 I can no longer move the mouse outside a limited/bounded region to the top left of the screen such that I cannot even get to the "Apply" button in the Settings menu to revert the resolution (have to Alt-Tab out, force quit, and change resolution in config file).

The bounded region that the mouse cannot move beyond gets smaller at higher resolutions. Therefore it seems like the mouse region can never extend beyond some limited area of pixels measured from the top left (1600x900?).
