Part of the recordings is black & white squares

[romgrk]

System Info

- io.github.seadve.Kooha 2.2.3
- Flatpak: false
- Experimental: false

- Distribution: Arch Linux
- Desktop Session: gnome
- Display Server: wayland

- GTK 4.10.1
- Libadwaita 1.3.1
- GStreamer 1.22.1
- Pipewire 0.3.67

Describe the bug
When I record a screencast, part of the recorded video is the black & white squares pattern shown in the screenshot. Which part of the video has that pattern goes from 10-90%, depending on the recording, and doesn't always fall in a precise place. It's usually not at the start nor the end of the video.

To Reproduce
Steps to reproduce the behavior:

1. Record a screencast with options: capture window, desktop-audio yes, microphone no, mouse no. Video format tried: webm & avi
2. After the recording has ended, the output video show the pattern when viewed in a video player (tried VLC and gnome player)

Expected behavior
No pattern

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
I didn't have the stuff below running with the recording, but I can create one with this enabled if you think it would be useful.

If applicable, please attach the logs from running Kooha in the
terminal with the following environment variables: `RUST_BACKTRACE=1 RUST_LOG=kooha=debug GST_DEBUG=3 PIPEWIRE_DEBUG=3`
(e.g., `RUST_BACKTRACE=1 RUST_LOG=kooha=debug GST_DEBUG=3 PIPEWIRE_DEBUG=3 flatpak run io.github.seadve.Kooha`).

It was working fine for me before, but suddenly I seem to only ever get the checkerboard, even in the area selection window

Thanks for reporting. This seems to be fixed by #235. Feel free to reopen if it is still reproducible. Thanks again!
