What do you mean by hardware issues? I am not sure if I understand you correctly.

Just to mention: I am testing the application on different systems which are running in their native resolution, e.g. 16:10 aspect ratios on a widescreen Dell Laptop running on 1680x1050px, 4:3 / 5:4 aspect ratios on Desktop PC running at 1600x1200px / 1280x1024px.
And if the application is not running in fullscreen mode it works.

The question that arises for me is if 3DGS is not designed to run application not using 4:3 aspect ratio in fullscreen mode.
