Solution 1:

Ok, I've found out what the issue was. UI scaling is handled by Qt in case of android emulator. It was set to: QT_DEVICE_PIXEL_RATIO=2 somewhere in my configs. This made emulator act weird. Cheers!

Just delete the environment variable and restart Android Studio to get the new env variables.
