Shared screen rotated when sharing from rotated (portrait) display

[jolars1]

I have a dual monitor setup with one screen rotated 90 degrees into portrait mode. When I share a screen from Zoom, using the PipeWire mode and xdg-portal-desktop-wlr (I'm on linux with the sway display manager), then the shared view is rotated (or unrotated, I guess, depending on perspective). Basically the shared view is incorrect and shows a rotated view.

PipeWire broadcasts buffer information about transformations since this PR: https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/1423. So the Zoom app should be able to handle this. OBS-studio, for instance, handles this gracefully and provides the correct screen shared view when used with PipeWire.

Here's a link to how grim, a screenshot tool, handles this transformation information: https://gitlab.freedesktop.org/emersion/grim/-/blob/master/output-layout.c?ref_type=heads

I hope that's helpful. I'm on version 6.3.11 of Zoom.
