Steps to reproduce

1. Install Focus Nightly 110.0a1 on an Android 13 device
2. Open youtube.com, or vimeo.com.
3. Start a video, then access the fullscreen option.

Expected behavior

The video is displayed in fullscreen without issues.

Actual behavior

The video is displayed in fullscreen, but the screen is white. The video continues to play, audio can be still heard, but no video. Tapping on the device's home button, triggers the PiP, that is still with blank screen.
NOT reproducible on the latest Fenix nightly 110.0a1.

Mihai, is downgrading the appcompat and material libraries a temporary fix? Do we need to leave this bug open to fix the video issue that's preventing us from upgrading to appcompat 1.5.1 and material 1.7.0?

Yes, it should be a temporary fix, we would still want to find out what causes the regression.

same issue but Video is working fine in my website https://www.travelmykashmir.com but not in youtube

I have identified the change that caused the regression after updating appcompat library.
While I already have a draft PR, I would rather have it merged after the next beta cut, so I am going to add the QA verify label in order to formally check if the already merged fix (libraries downgrade) has resolved the issue.

Verified as fixed on Focus Nightly 110.0a1 from 1/5 from https://firefox-ci-tc.services.mozilla.com/tasks/index/mobile.v3.firefox-android.apks, and on Beta 109.0b6 with Google Pixel 6 (Android 13).
