KDE with disabled compositor, i3, etc. use alpha visual, but it's not transparent. Could -moz-gtk-csd-transparent-background be defined with gdk_screen_is_composited() and be used to forbid outer border-radius + outer shadow of main menu/addon/etc. widgets to remove any Xshape usage (bug 1730991 comment 6)? According to the Chromium bugtracker, Xshape also causes performance problems (bug 1730991 comment 7). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1871644 Title: Top corners of Firefox windows have weird black protrusions from the rounded edges Status in Mozilla Firefox: Confirmed Status in firefox package in Ubuntu: Confirmed Bug description: Image to illustrate the problem is attached. All firefox windows on Wayland (EDIT: and X11) 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.
