Finally, I guess i found a way to fix this:
1- Right click on the Cakewalk icon on your desktop and select "Properties".
2- Open "Compatibility" tab, then select "Change High DPI Settings".
3- Check "Override High DPI Scaling Behavior", and choose "Application" from the drop down menu.
4- Click on "OK" and apply your settings.
Here are the results on my 15.6" laptop screen:
