After updating Android studio to version 3.1.2 an issue popped up where the preview image is, pixelated/blurry. Can anyone help me fix this issue?
This is how the image is rendered

I have encountered the same problem in Android Studio 3.3 but fortunately I've managed to find a solution. You have to go to "Help" and click on "Edit Custom Properties". It might ask you to generate a file if it doesn't already exist. Once this properties file is made, you will need to write "hidpi=false" (no quotations). Save it and restart Android Studio. When you open it again , you still need to do one thing: go to File then Settings, type font in search box, select font from editor then change the size of font to 15. (or what ever size you prefer). That's all.

I solve this problem pretty easy after learning documentation.
You need to change your scale display parameter. Because Android Studio supports only certain scale. Use 100% or 200% and your design tab in Android will be sharp again
