[goddard@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.22631
ChimeraX Version: 1.10.dev202502220014 (2025-02-22 00:14:16 UTC)
Description
Display slept after about 5 minutes idle when connected to Sony Spatial Reality display with "xr on".  After waking display ChimeraX menus and commands still functioning but graphics frozen, and Sony display is black.  Using "xr off" then causes this crash.
Please describe steps that led to the crash here.

If I don't wait for the display to sleep then "xr off" works correctly and a subsequent "xr on" also works. Apparently the crash happens when OpenXR disconnects and then we try "xr off".

[Tom Goddard]

These warning messages

xr.wait_frame() or xr.begin_frame() failed

are sent to the log at maybe 60 or 90 per second and probably our OpenXR code should limit them since updating the log may eventually cause ChimeraX to become unresponsive. But that is unlikely to be related to the crash.

[Tom Goddard]

Putting in a print statement when OpenXR gives an exiting message does not ever get printed. So it seems OpenXR shuts down without sending an event. Then probably the xr.shutdown(session) call crashes because it is already shutdown. Maybe there is an OpenXR call that can query if the session is still valid.

[Tom Goddard]

The same crash is produced by showing a model with "xr on" then turning off the Sony display. The Sony OpenXR driver then logs a display disconnected message within about 1 second. Turning the display back on and the ChimeraX graphics is frozen, but menus and the UI works, apparently it just can't begin a frame. At this point using "xr off" crashes ChimeraX in xr.destroy_session().

If I add

xr.request_exit_session(openxr_session)
xr.end_session(openxr_session)

before the call to

xr.destroy_session(openxr_session)

then ChimeraX does not crash, the Sony OpenXR window showing the molecule disappears and a subsequent "xr on" works. Both the request exit and end session calls are needed. Doing only end_session() generates an OpenXR error about not being in the Stopping state. Calling only request exit does then destroy session crashes. Calling just request exit does not remove the molecule from the sony display and a subsequent "xr on" gets errors trying to create a new session apparently because the old session is still present.

[Tom Goddard]

Fixed.

I added the request_exit_session() and end_session() calls before calling destroy_session() if the system name is "SonySRD System". This seems to be a bug in the Sony OpenXR implementation.
