Emulator: System UI isn't responding, horrible app glitches

I have multiple emulators provided by Android Studio. I have a Pixel 3 and a Pixel 4 both running Android api 30. Both work fine for a while, but eventually there is this popup: System UI isn't responding

After this point, the emulator becomes unusable. Notice that the home and back buttons at the bottom of the screen are gone. The emulator glitches horribly, with animations slowing down and leaving residue on the screen.

What I have tried

Quitting the emulator application and turning it back on again. Same issue again.

Pressing the emulator power button and restarting the emulator like I would a physical device. Same issue.

Deleting the emulator and creating new one. This works for a while but eventually the error happens again.

I followed the advice here: Android emulator error: "System UI has stopped" The .ini file had no entry for hw.mainKeys so I tried adding it. No effect.

At this point, it's becoming difficult to continue development, since I have to keep recreating my emulator and reinitializing the device data that I need for testing.

The fixes reported by some users are in the following list. However each of the fixes have worked only for some small group of users.

  • Update your HAXM version (check manually in SDK manager)
  • Use a lower resolution emulator
  • Try a different API version or system image

The only fix that works for all users is to wipe your emulator and start it again (which means setting up your accounts again). This fixes it for short times but the problem always returns pretty fast.

The problem has been common since at least late 2017, on both windows & mac. There was a starred issue on Google bug tracker too but I cannot find the related question on StackOverflow which linked to it
