I'm also seeing the pattern when logged-into X11 (note there is a difference in the image because in Wayland I have the monitor set to 200% scaling while in X11 it is set to 100%, so the images have different numbers of pixies for the bug)
** Attachment added: "top-right corner of a Firefox window on X11" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1871644/+attachment/5349685/+files/ffbug-x11.png ** Description changed: Image to illustrate the problem is attached. All firefox windows on Wayland have a weird black protrusion from the top-left and top-right corners where yaru has curved the window corners, but something from Firefox appears to not be being clipped by the theme. I need to double check whether this appears on X11, but for now consider it Wayland only until I report back, although oSoMoN has checked their system and they don't see the behaviour (on X11). + + EDIT: I have now checked X11 on my system and I see the same behaviour + as described above, so this is affecting BOTH Wayland AND X11 for me.
