This is where it gets even more confusing, I cannot reproduce the issue using "Xephyr -glamor"... Not even with Xephyr running in Xwayland. I can reproduce on Xwayland though (I mean, running another Xwayland server in a Wayland session), I can capture an apitrace of that, but the apitrace looks incomplete and cannot be replayed (no context).
