            Bug ID: 260259
           Summary: Video texture not updating after entering WebXR mode
           Product: WebKit
           Version: Safari 16
          Hardware: All
                OS: Unspecified
            Status: NEW
          Severity: Blocker
          Priority: P2
         Component: WebXR
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: filipesnetopires at ua.pt

I've been reading several unresolved threads regarding video playback issues with WebXR (example thread here: https://discourse.threejs.org/t/video-texture-no-longer-updating-after-entering-webxr-mode/43068).
Has this been addressed or is it on the radar and road mapped already? Is this an appropriate place to raise the issue?

The issue I'm personally facing relates to Vision Pro's Simulator and its Safari version.
When trying to playback a video texture, everything works fine in the browser's ThreeJS 3D viewer, but as soon as I enter WebXR mode, it freezes on the last frame until I exit immersive mode.
A related Stack Overflow thread is available here: https://stackoverflow.com/questions/76577886/video-playback-html5-videoelement-apple-vision-pro-simulator-in-vr-mode-not-pl.
