Bug description

When screensharing it brings up prompt, but output of screenshare is entirely messed up with jagged lines going down (See Video)

Additional context

Not using Wayland works fine, but not really a solution if you want to use wayland. Also additional notes: Chromium crashes when trying to screenshare weirdly enough. (Might be releated?).

Video: Recorded with pipewire video capture:

Verbose output from webcord when first screensharing: Problary releated:

[11511:0615/151242.681968:ERROR:egl_dmabuf.cc(569)] Failed to record frame: Error creating EGLImage - EGL_BAD_ALLOC
[11511:0615/151242.682063:ERROR:shared_screencast_stream.cc(598)] Dropping DMA-BUF modifier: 72057594037927940 and trying to renegotiate stream parameters

I can screenshare from Firefox, and also Obs pipewire output (Which is how i recorded in first place)

To be clear: I have tried running master branch but couldnt get it working, and also i dont seem any commits that would seem to be related to this issue

seems to be upstream in chromium and electron confirmed: in xdg-desktop-portal-wlr https://github.com/emersion/xdg-desktop-portal-wlr/issues/217 downgrading xdg-desktop-portal to 0.50 works. It’s a deep rabbit hole, Webrtc seems to be the problem though

Looks like the fixes have been deployed in Chromium version 105. It looks like upgrading PipeWire might also fix the issue for some.
