Choopy Desktop Capture using Pipewire and OBS Studio 30.0.2 on Wayland

Hello there, when attempting to record your screen using OBS Studio 30.0.2 and Pipewire Desktop Capture results in an extremely choppy and laggy recording. The desktop it self is fine.

I attached a video recording a 3rd display using a capture card and pipewire to better visualize the issue.

Driver: 545.29.06
Desktop: Gnome 45.3 / Wayland
Kernel: 6.6.10
OS: openSUSE Aeon
OBS Studio: 30.0.2 (older versions had this issue as well, in fact I don’t know a version which worked)

Running driver 550.40.07 it gotten better but still it has a lot of frame drops in the capture. Desktop itself is fine.

Gnome 45.3
Kernel 6.7.2-1-default
PipeWire: 1.0.2

Applications running in any form of fullscreen do not get updated in the capture at all:

My guess is it has something to do with Mutter redirecting fullscreen windows directly onto the screen instead of compositing them.

Yep, with the Gnome extention Disable unredirect fullscreen windows the capture does no longer skip fullscreen applications:

Driver: 550.54.14
OBS Studio: 30.0.2
PipeWire: 1.0.3

Desktop capture still choppy. In fact unchanged from what could be observed on 550.40.07. At least it didn’t got worse.

Probably a long shot, but if you specify the env variable export __GL_YIELD=USLEEP does it fix the issue ?
I have that specifically set for kwin(in /etc/profile.d/kwin.sh) and it has been working super good.

Thank you for the suggestion.
I added this to my .bashrc and rebooted but it did not helped.

I have this same issue from months

Same issue. The only way to bypass this issue is record with obs-vkcapture for me

I think it’s an OBS issue, because GPU-Screen-Recorder works perfectly without stutters, but sadly they dismantled my bug report and completely ignored it

Do any of you guys know if this issue can be related to Gnome MUTTER? or an issue with Pipewire directly?

This needs to be fixed, I still have this issue with drivers 565 and OBS 31-rc1

Hey guys I have an update.

I’ve finally discovered that this bug is releated to GNOME only, as I don’t get it on KDE Plasma and the recording is smooth there.

I’ve made a bug report 2 months ago to Gnome and recently a user replied to me and attached a screenshot of gnome shell giving some errors when recording with obs and proprietary nvidia drivers, so it’s confirmed that it’s a gnome issue only and it’s up to them to fix it
