Screen sharing in video conferencing software (bbb, webex, meetme etc). It just doesn't work consistently. Sometimes (rarely) it just works as expected. Sometimes everybody sees a "black screen with a mouse pointer". Sometimes your screenshare is tiny and squeezed into a quarter of the virtual screen. Sometimes it's enlarged instead and doesn't fit into the virtual screen. Sometimes the popup (Wayland recording bridge???) doesn't show up. It's russian roulette basically, this shit definitely needs more eyeballs.
