Pixelated Editor Preview

Hello! I've just downloaded the app again and was making a new file when I got this issue.

Whenever I choose a background image in the root folder, it gives me a very pixelated preview of my selected image. I've tried reinstalling both the main app and the pro key or using a different image, but to no avail.

Any help would be appreciated.

I am using a Xiaomi Mi A3, if that helps.
