Doubtful this is an xdg-desktop-portal-kde issue. We have a similar report in Bug 461247 too.

Maybe yeah.. I thought xdg-desktop-portal-kde was responsible in this case.. however in that bug is kinda different than this one imo because in this case X11 works perfectly fine (even with compositor on).. not to mention other DE like GNOME Wayland is perfectly fine.. if need more details.. just reply me

This is a problem with our implementation. Either here or possibly in KWin.

This is also a problem with firefox/chromium window sharing.

Marking as confirmed because it needs attention in a way or another, it's just not clear to me what's the right way to fix it.

Did you move OBS's window to a different virtual desktop? If so, it could be Bug 456280.

When I checked the resizing bug on my machine I did the test on the same virtual Desktop. I have a 3 monitor Setup and i only use one Virtual Desktop. I have a 2nd one enabled but don't use it. For my System details see my earlier post.

Nope.. its on the same desktop..

screencast: Fix how we tell pipewire that the stream has been resized

We need to send sizes in a format that param buffers understand.
This fixes some glitches we'd see when sharing a window and resizing it.

Thanks Jan Grulich for pointing me in the right direction!

Explanation why this is opened again.. The bug isnt got fixed with 5.26.4 update.. maybe with little video i can show what is exactly the problem is

KDE Wayland OBS Example  https://youtu.be/KditmAFcLj0
GNOME Wayland OBS Example https://youtu.be/L0cHQ5dukaY (Same behavior can be replicated on KDE X11)

This looks to me like OBS needs to react to the buffer changing size.

We implement it different to how GNOME does it so it might need addressing in OBS.

Alright.. i will try to report a bug in OBS and see their response..

Already reported in OBS Github Issues.. maybe we can follow it there?

https://github.com/obsproject/obs-studio/issues/7875

Yes, I subscribed to the issue and will be following closely.
