Fix for Red Old-Style Emulator Display & Zoom Issue in Android Studio 3.1

Hey there! I’ve dealt with this exact annoying problem right after updating Android Studio to 3.1, so I’ve got a few tried-and-true fixes to share with you:

Check and update the emulator skin
Open your AVD Manager, find the problematic emulator, click the "Edit" button (the pencil icon). Under the "Skin" section, ditch the default generic skin and select one that matches your target device (like Pixel 5, Samsung Galaxy S21, etc.). Save the changes and restart the emulator—this usually gets rid of that red old-device look right away.
Adjust the emulator zoom level
Once the emulator is running, click the three-dot menu icon in the top-right corner. Go to the "Scale" option and slide it to your preferred percentage (100% is a good starting point). You can also use keyboard shortcuts: press Ctrl +/Ctrl - (Windows/Linux) or Cmd +/Cmd - (Mac) to quickly zoom in/out until the display looks normal.
Update the Android Emulator tool
Sometimes the issue pops up because the emulator version isn’t synced with the new AS 3.1. Open SDK Manager (go to Tools > SDK Manager), switch to the "SDK Tools" tab. Look for "Android Emulator"—if there’s an update available, check it and click "Apply" to install. Restart Android Studio and launch the emulator again.
Wipe AVD data to clear cached issues
If none of the above works, head back to AVD Manager, click the dropdown menu next to your emulator, select "Wipe Data". This resets the emulator to its initial state, which can fix weird display glitches caused by cached configuration files. After wiping, restart the emulator.
