Hi,
Did the issue occurred once the XP mode was installed?
Please make sure the Intergration Features is enabled. Also check you have set maximize correctly. Here are the steps.
1. Run Windows XP Mode.
2. On the windows, click Action, View full Screen.
3. With this simple operation, Windows XP Mode Virtual machine will remember the position and resolution of the window on exit.
4. Done!
If the issue persists, I suggest updating the graphic card driver from the host PC to check the result. Also change the Screen Resolution for testing.
If the issue persists, you may need to reinstall Windows XP mode.
