Déjà Vu window is blurry in Windows 10

Doing this will affect everything on your screen! Depending on the size and resolution of your screen, you may find that text is too small to read comfortably.

If you find that the Déjà Vu windows is blurry, you likely have Display Scaling in Windows configured to a value higher than 100%. Since, at the moment, Déjà Vu does not support display scaling, Windows will just stretch the Déjà Vu window and its contents to make it bigger, much as an image editing application would scale an image, and this makes it look blurry.

To prevent this, you can change the Display Scaling options in windows so that it will not scale up any applicationsnote, or you can configure the DVX3 executable to ignore the Display Scaling options and set a scaling factor of 100% for it.

    This was not just helpful - it was miraculous (especially in light of my struggles with display scaling for the whole computer when I first got it)!
    Thank you, lovely Atril!
