Steps to reproduce:

  1. Open mp4 in firefox (on bugzilla)

This only happens with the first mp4 opened after the app is opened.

This also happens on PC

Thank you for the report!

I was able to reproduce this issue on the latest Fenix Nightly 128.0a1 from 5/29 using a Realme GT Master Edition (Android 13) device.
NOT reproducible on Beta 127.0b7, nor on Firefox for Android 126.0.1.
The glitch was displayed, as mentioned by the reporter, just the first time I've opened the .mp4 file.
I'll confirm this ticket.
