Per-Monitor DPI Awareness

If I drag the Splashtop window from one monitor to another and the two monitors have different DPI values, the Splashtop window does not resize. So, going from a low DPI monitor to a high DPI monitor, the window becomes small. Or, if the last time I ran Splashtop I was on a high DPI monitor and now I start it on a low DPI monitor, the window is too large and I have to resize it to make it smaller. Splashtop should take the monitor DPI value into account when saving and restoring the window size and redrawing the window when it moves to a different monitor. 

Windows provides support for this via "Per-Monitor (V2) DPI Awareness":
