This is a driver bug in Oculus Runtime 15. There is nothing we can do about it until oculus fixes the driver.

My quest must have received and update today as the issue is no longer happening on my device.

Please make sure you have the most recent update that includes the bug fix and retest.

Sorry, it was not fixed for me with a software update, but we have confirmation from oculus that it is their bug and will be fixed in v16.

Oculus has recommended a work around that appears to work.

I have verified this issue and it's no longer reproducible with the latest Firefox Reality version 10-140982354 (bce60f9) build. The transparent background around the buttons/prompts and menus is no longer displayed.

Tested on Oculus Quest (Android 7.1.1) and Oculus Go (Android 7.1.2) devices.
