Hi, I installed Debian 12 on my laptop. I'm using Firefox 133.0.3 from Flatpak. When the browser is in full screen and I display a video in full screen mode, strangely, the video is not in full screen... It's on the top left corner and the rest of the page is in violet. I tested on different site, loading a local video and the issue is the same. I can't reproduce the issue on my desktop computer on Windows. When the browser is not in full screen (F11) and I put the video in full screen mode, there is no issue... I attached a screenshot of the situation. Have you ever encountered this kind of issue? How to resolve it? Thanks
