2.3.0.0 64 bit, ALT+Tab / Loss of focus causes black scene

[Eric.B]

With OpenGL and Dynamic Report Size checked. 1920x1080
I have to manually scroll to read sales figures

Yes, you will have to scroll down to see the full sales report. I would be surprised if you didn't have to at any resolution smaller than 4k.

Also note, GUI Scaling will increase the web browser zoom levels. If you want the Browser to be as small as possible, use the smallest zoom level.

EDIT: Also to point out, because you're resolution is less than 1050 height, the game is using the small reports window, thus why the browser controls are at the bottom. Reduce your Windows Taskbar size, or set it to auto-hide before launching the game.
