Just me? Any seeing a reduced screen resolution when running the desktop app?

Windows 10 1803, SD 3.11.0

OK, a bit of googling and reddit came up with a solution.

It's all to do with the way windows 10 handles DPI scaling. See here http://windows10_dpi_blurry_fix.xpexplorer.com/

I followed their advice and turned off scaling for SD and that fixed it.
