eDrawings not displaying window correctly

I don't mind the changes to the eDrawings interface, but there is something weird going on. Is it just me?

When eDrawings is maximised the main window is not centered on the frame. I get the window border on the edge of my screen, but the window contents are offset, and I can see (and select!) items behind it (i.e. within the border).

I'm running Windows 7 x64, SW 2015 SP3, and an ATi Firepro V4800 with two monitors. Details of error below...

View of two windows open, restored and centred on each monitor:

Both winows maximised, but desktop visible and selectable due to offset.

Is this a driver issue? Are 2015-compatible drivers not available for my GPU?
