The problem is that there is nothing that prevents the render loop to call xrWaitFrame() and the rest of the methods before the session is actually started. WebXR code can properly setup the frame update callback before the OpenXR session begins, and thus the render loop would try to call xrWaitFrame()->xrBeginFrame()->xrEndFrame() on a session that hasn't started yet. 2128191 1 svillar 2025-07-07 10:17:58 -0700 Pull request: https://github.com/WebKit/WebKit/pull/47666 2128402 2 ews-feeder 2025-07-08 01:39:13 -0700 Committed 297102@main (c2db6f72f6cd): <https://commits.webkit.org/297102@main> Reviewed commits have been landed.
