#1406 Windows 10 dpi scaling has blacked out regions

[C-F]

The environment is as follows:
Windows 10 laptop with native screen resolution of 1366×768.
Connected to HDMI monitor with native resolution of 1280×1024.
Between the laptop and the monitor is a HDMI to VGA/DSUB adapter because the monitor is analog only.
Scaling is set to 150% (similar problem when scaled at 125%).
Attached is an image of Google Chrome incognito window, maximized, on a Youtube video.
You can still click things in the black region, but can't see what you're clicking.
DFMirage is installed.

Dual montior mode is set to 'duplicate'.
Visible area is 960×768 pixels.

I'll try to reproduce.
BTW, there is no need in mirror driver since windows 8.

Add that BTW to website after DFMirage download paragraph? ...DFMirage is FREE for you as well. (Not needed since Windows 8)

The status for this issue has been "open" since 2016, are there any plans to fix this in the coming TightVNC releases? Can you please update me? We are using the latest version of TightVNC and are facing this issue regularly in case of windows DPI changes on a multi-monitor setup in EXTEND mode, any of the workarounds listed, are not seeming to work for us.
