Bug Description
Since updating to Ubuntu 22.04, OBS (27.2.3+dfsg1-1) has become unusable for recording:
- the screen capture (pipewire with xdg-desktop-portal) is very laggy: when passing slides on the captured screen, OBS stays stuck on previous frames
- the sound input (pulseaudio) is crackling, even though it works perfectly well when recording the same source with pw-record.

Notes:
- I tried to switch to Xorg: the screen capture works well, but the sound crackling is even worse (probably because the CPU is used more heavily under Xorg due to fractional scaling)
- Everything worked fine under Ubuntu 21.10 (with OBS 27.0.1+dfsg1-1)
