Flutter run doesn't work with the Android Emulator with Hardware Rendering (Linux)

[Pacane]

Steps to Reproduce

• In Android Studio:

  • Create AVD (Any API level as I think) (I used a Pixel, Android 8.0 with API 26).
  • Set Graphics to Auto or Hardware - GLES 2.0
  • Launch the emulator
  • The Emulator launches properly
    

• In command line:

  • Flutter run
  • The app runs, but the screen is black. See screenshot

Although, if I use flutter run --enable-software-rendering the app shows up properly, but is running much slower obviously.

Operating system details:

• Using Arch Linux with up-to-date Nvidia drivers (v.384.69). (App loads as a black screen when using hardware rendering)
• Using Mac OSX with I don't know what drivers (App loads properly with hardware rendering)

Other information

• This seems to be a flutter issue, since I've tried running a regular Android app from Android Studio and it works fine.
• For what it's worth, I've tried loading multiple apps, so the issue doesn't seem to be with my app.
• Also, this used to work about a week ago, either before upgrading flutter or my system config.

Thank you for the very detailed bug report. @chinmaygarde @jason-simmons

[eseidelGoogle]

My understanding was @chinmaygarde made a recommendation at some point that we should default to software rendering for Android emulators? I can't seem to find it.

[xster]

If it's not the default mode, we might need a way to opt-in from IDEs as well https://stackoverflow.com/questions/49049915/flutter-sample-app-not-working#comment85106918_49050620
