Short description of error
When using Blender on two monitors with different DPI, header menus will disappear when switching between workspaces. Also UI scale doesn't refresh properly.

Exact steps for others to reproduce the error
different_ui_scales_bug.blend

In Windows 10 set custom scale on the second monitor in Display Settings > Scale and Layout, for example to 175%, so that each monitor has different scale.
Put one Blender window on each monitor (same Blender session).
Switch between different workspaces tabs.

@Harley Is this the type of bug you said to watch for in D6370?

@EAW - @Harley Is this the type of bug you said to watch for in D6370?

No, the Windows 10 feature addressed in that patch (when working correctly) only affects the non-client area (the titlebar surrounding blender). When dragging a window from one window to another one with a different DPI setting that outer titlebar will change height to match. When NOT working correctly (caused only by using an old Intel driver), then the mouse pointer differs from where it operates by a distance equal to that vertical size change in the titlebar.

This issue doesn't seem to be at all related, but I'm not sure what this is. I always wonder if we'll have trouble caused by us storing monitor dpi globally instead of by monitor.
