Hello there,
As you are noticing this only in one device you might compare the display settings and try to revert back to the same.
You might also need to check your performance and power setting which plays a key role here.
Go to Settings:: Ease of Access:: High Contrast and turn off the High Contrast theme and see if that helps.
If Windows Update recently made updates to your device, roll back your display driver. Otherwise, try updating or uninstalling your display driver.
Hope this resolves your Query !!
