I have verified this issue and it's no longer reproducible on windows having the 3x, 2x and 1x size.
However, this issue is still reproducible on windows having the 0.5x size.
Tested on Oculus Go (Android 7.1.2), Oculus Quest (Android 7.1.1), HTC Vive Focus Plus (Android 7.1.2) and HTC Vive Focus (Android 7.1.2) using the latest Firefox Reality version 8-40101959 (3c2a71e).

Considering this I will reopen this issue.

I have verified this issue and it is no longer reproducible with the latest Firefox Reality version 8 RC1 build (7a444d0). The 0.5x windows now display the proper layout while loading.
Tested on Oculus Go (Android 7.1.2), Oculus Quest (Android 7.1.1), HTC Vive Focus Plus (Android 7.1.2) and HTC Vive Focus (Android 7.1.2).
