Even though rendering always happens in Canvas’s GL frame buffer, VR mode 13 should now theoretically work as GLFramebuffer can be told to use a different swap mode for the left/right frames.
In practice, the “left” swap mode draws the contents of the Canvas frame buffer into the window’s BACK_LEFT buffer; same goes for the “right” swap mode. The “stereo” swap will then simply do a regular back-to-front swap with the finished contents.
