Answer 1

Ok so you need to disable windows 10 scaling for this app. While its running find it in task manager. Right click on "Android Emulator - [Device Name]" and chose open file location. You should now see the folder with the emulator exe highlighted. Now Right click on the exe and open properties. Then go to the "Compatibility" tab. Now open "Change high DPI settings". Here's where the magic happens. Use these settings, Of note is scaling preformed by "System" this means that we wont trust qemu to do the scaling (which it ignores and causes the problem)

Not that it will be blurry, with big pixels. But at-least the mouse aligns with where the image is. – Clariceclarie

Answer 2

I ran into the same issue. In your Virtual Device Configuration window, set Emulated Performance to Software

It seems that if you're using Hardware Acceleration the scaling goes all wonky.

Good luck

*Note: From what I've been able to test myself, SDK Level 24 is the highest you can go with Software acceleration. If you try running at SDK 26 or 27 you'll get some weird artifacts or lines across your simulator screen. This solution isn't ideal, but at least it's more usable than the mini-screen you get with hardware acceleration.

Sorry, but it's really not a solution. Emulator without hardware acceleration is not usable at all. – Loathsome
