This fix (adjusting the High DPI .exe Compatibility Settings per the previous post) is not working for me. Are there any other potential fixes.

UPDATE: Solved ---  Uninstalling with REVO Uninstaller, having it clean leftover items and letting it clean the Registry and reinstalling fixed the issue. Settings for the .exe are default, "not modified" per the earlier post.

Now @mouser, 'shift+prtscr'

It still massively enlarges the screen on capturing. Not solved but the Beta.

So you know how I'm running it, I didn't uninstall my production version (that is not installed as Portable). I just made sure it was terminated and then I launched the Portable Beta. I assume that's OK.

Lastly, for both issues, I tried running as 'Administrator' when I launched. No difference. Although, my entire machine is set to Administrator so that's probably moot.

I'm still having the scaling problem. I have three monitors, all set to 100% scaling. Two are 4K and one is a 2K monitor. If I try to 'shift-PrnScr' on the 4Ks everything is scaled up and shifted off screen so I can't drag and get the lower right corner. Plus, it's just enlarged really big.

I've completely uninstalled and reinstalled, and rebooted, on my Windows 10 Pro machine. No help.

I tried using a 'Manifest' file to change the DPI detection to 'false' just to see what happens, that did not help. Not sure it even would, just a stab in the dark. You never know when you are not a skilled coder...lol...

I've changed to the mode where you get a red overlay that you can size and then hit 'Ctrl+click' to grab, but then that window freezes and hangs and I have to use Task Manager to close the program and reopen it.

So I'm kind of stuck. I love SC but I think I have to find another solution now.
