Android Studio gets high DPI wrong in so many different ways. Also presents this warning which is basically untrue, and coins a new word "seriousperformance" which I assume is a trademark meaning the opposite. Overall the app just hurts to use.
ALT Windows Dialog with Icon, Button and Checkbox that are three time bigger than they should be. Message reads:
"The ADB binary at C:\Users\user1\AppData\Local\Android\Sdk\platform-tools\adb.exe is obsolete and has seriousperformance problems with the Android Emulator. Please update to a newer version to get significantly faster app / file transfer".
