All I want for Christmas is for the Zoom Linux client to fix screen-sharing.

Zoom is becoming a busted, unworkable application on modern Linux desktops. 

Linux systems are quickly and aggressively moving to Wayland & Pipewire for graphical sessions because they are more secure than the outdated, fragmented x11 standards.  In fact, more and more Linux distributions are going Wayland-only, or at least Wayland by default. KDE and GNOME are both deprecating x11 support.

Zoom has not kept up.  The screen-sharing problems on the NVIDIA/Wayland/Pipewire/Zoom stack are well-known and well-documented.  You basically share a black screen that crashes your call when you stop sharing.  The settings menus are not helpful (and yes, I have tried all of them).  Screen-sharing just doesn't work well on the Linux client with very-common hardware and OS configurations, and the only workaround is to run it on an x11 session.  This is a notable defect, and the problem really appears to be contained to Zoom.
