https://bugs.kde.org/show_bug.cgi?id=471364 --- Comment #7 from toby --- >From the bug report I mentioned earlier Prajna Sariputra is reverting commit 226d8c0a3b464f8870c45bfe5079f042a3cd5d67 in kwin, I've just done that myself to see if it resolves this issue and from what I can tell I'm not getting any stuttering. -- You are receiving this mail because: You are watching all bug changes.

Thanks for commenting toby. Yes, when any window/screen sharing occurs, regardless of whether it's by the portal sharing selection dialog or a currently active source, I can see a single thread being pinned at max utilisation. I can see the kwin_wayland process maxing out at 4% utilisation which, on my CPU with 24 threads, lines up with the almost 100% utilisation I'm seeing on a single thread. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=471364 --- Comment #3 from deadmeu --- It's worth noting that this issue doesn't seem to occur when using a Game Capture source using obs-vkcapture (and obs-gstreamer). -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=471364 --- Comment #2 from deadmeu --- Created attachment 159888 --> https://bugs.kde.org/attachment.cgi?id=159888&action=edit pipewire connections I've tested this issue a little more and it looks like this issue affects the Screen Capture Source as well. When you create a new Window/Screen capture source the Screen Sharing Portal dialog pops up with previews of the windows/screens to choose. This is when the stuttering begins. If you cancel out of that dialog the stuttering goes away. Also, I tried disconnecting all of the pipewire screencast streams using qpwgraph while I had the Screen Sharing Portal preview dialog open to see if that would kill the stuttering (there are multiple win_wayland [kwin-screencast-...] sources connected to xdg-desktop-portal-kde [plasma-screencast-...], kwin_wayland [kwin-screencast-...], and plasmashell [plasma-screencast-...] sinks, see the attached screenshot) but that did not work. -- You are receiving this mail because: You are watching all bug changes.
