Thanks for reporting this bug. Knowing this is a regression in GeckoView 68 is helpful.

This is a possible cause of rendering failure when app with GV gets started and phone's power button pressed before app finishes startup.

1. start the app
2. press power button to turn off phone's screen
3. wake device (using for ex: fingerprint scanner)

the rendering failure result is the same as described above

Happy to take a patch for 70 but since this is triaged and set to P3 priority I'm setting it as fix-optional.
That will remove the bug from weekly regression triage.

another way to reproduce the problem is something more common in term of actions:

1. start the app
2. while it's loading, press the "menu button" on the phone (to look at current loaded apps)
3. go back to the app

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
