That doesn't sound right. A 15" will be 1920x1080 by default. Try the following:

Windows 11:
Settings (Winkey+i) > System (left column) > Display (right column), scroll to Scale & Layout and change to 100% if it isn't already. While you're there, check to see if the Display Resolution is set to 1920x1080.

Windows 10:
Settings > System > Display look for scale and layout. Check Display Resolution.

Try Xara and see if you can now see the Go Away button. Reset back to what had in the settings if you need to.
