Poor performance when screensharing under Wayland/Pipewire

Hi, I'm encountering a somewhat annoying bug with screensharing under Wayland/Pipewire. The issues are present under OBS and Discord, and arise when I try to screenshare using Pipewire.

For OBS, I encountered that selecting a specific program or window does not cause any issues; no performance drop, no low FPS on the recording. It's pretty smooth.
When I record the entire screen, I encounter issues. Notably, the game's FPS on the recording are choppy, however, I notice that the cursor's FPS are just fine. Again - only issues with entire screen, not present when selecting a specific window.

The same is true for Discord and other clients such as vencord, where my stream appears to have performance issues when selecting an entire screen.
On Discord (official client), my stream is OK for a few minutes under "select entire screen", and after a while, audio becomes choppy.
On Vencord, when I select the entire screen, the stream will not be OK, as it suffers from poor FPS.

I'm thinking it's something to do with the server being overloaded?
