I'm not sure whether that's limited to XWayland or applies to Xorg in general.
Can you try with with https://patchwork.freedesktop.org/patch/242409/ applied on Mesa? You should be able to reproduce with "Xephyr -glamor" as well, so not Xwayland specific (actually, I think this is mesa swrast code, the the patch above)

Well, I don't understand. I can't reproduce now...
