Wayland screen sharing broken on high-res (beyond 1080p) displays
I am on Fedora 36 using Zoom 5.11.9, using GNOME under Wayland. Normally I perform most of my work on an ultrawide 3440x1440 monitor. When I attempt a screenshare from this resolution, it appears that most, if not all people in the call (who are likely probably running at 1920x1080 or 1200) aren't able to see my screen. From the attachment, my screen appears distorted in the eyes of others in the room. I have noticed that if I scale my resolution down to 1920x1080 (which is my laptop displays' native resolution), my screen appears just fine. So I'm going to rule this down to Wayland and resolutions beyond 1920x1080 (or 1200). If I run an X11 session, I notice that the screenshare scales down to fit 1080p monitors, but is otherwise perfectly visible. This is sort of the behavior I was hoping for under Wayland as well. If it matters - I am connected to the external monitor via DisplayPort. I've tried setting the refresh rate to 60 or 100 hz, but that had no effect.
