I still have problems with screen sharing on a Zoom meeting.
I have connected with Chromium free world, and there were no windows to share.
Then I installed Chrome and connected to the Zoom web meeting with it. I could see some of my windows, but I couldn’t see Firefox in the possible windows to share.
Is there a reason you expect screen share in Zoom to work on Wayland? There’s been no announcement that they support it yet. Or are you referring to another issue?
