Problem with default resolution and scaling

[Pipsqueak737]

I bought the emulator a couple of days ago and it looked completely fine. When I opened it today, however, the screens zoomed in and I had to reset them. Now the default resolution (along with anything I scaled it to) changed to be non-uniform and somewhat jagged. What happened, am I able to fix this?

Edit: I'm now pretty sure it was an issue with my phone's battery saving mode, so never mind.
