Also reproducible with `mozregression --launch 2021-09-29`. Enforcing SW WR for popups was an incomplete workaround. Non-default Firefox themes can also cause non-round/non-transparent window corners on Mesa and Nvidia - doesn't seem to be a graphics bug there. 2) this is the only regression you spotted with this patch? No regressions were caused by this patch. I'll test bug 1732443 in 9 hours.
