1801935 - Video orientation wrong when in full screen

Status: UNCONFIRMED

(Core :: DOM: Device Interfaces, defect)

Description

[intheam]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:106.0) Gecko/20100101 Firefox/106.0

Steps to reproduce:

I use a 2 in 1 laptop, running Fedora 36 with KDE Plasma. Steps to reproduce:

1. Flip laptop upside down
2. Notice orientation automatically detected by KDE and everything flips correctly
3. Open firefox and play a video (YouTube, for example)
4. Set the video to full screen

Actual results:

The upside-down orientation is reverted to the natural orientation of the laptop, so it appears upside-down, incorrectly.

Expected results:

The orientation change should be accounted for when playing a video in Firefox in full screen.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Sounds like poor handling of orientation events, likely in front end code.

When not in full screen is the Firefox UI flipping as expected?

This is the UI while not in full screen. Everything is normal, and the screen is "upside down", as expected.

When full screen is selected, the image flips improperly.

When the screen is tapped (I am using a touchscreen), the UI flips briefly to the proper orientation, but then flips back. The screenshot shows a press and hold, the equivalent of a right-click.

Yes, when not in full screen, the Firefox UI is as expected. I have added screen shots to show what it looks like on my end.

Adding the Qa Not Actionable for now until we get our hands on a flip laptop, also I will change the component to Core Dom Device Interface, if its not the correct one we can move it back to General but ive seen a few issues on that component related to Orientation, is that Component specific to mobile devices ?
