Screen recording does not work well in Wayland. Black screen with the mouse cursor. Keeps breaking in Chrome and not even working in FF for me with Google Meet. Haven't used Zoom in a while, but prob still broken.
On Gnome Wayland, if you play Sonic Mania, you can feel the latency from when you push a button and Sonic jumps. From what I hear on Linux Unplugged, the latency also exists in other games. KDE Wayland is too broken to try.
