Bug: Doesn't work with Wayland

[hulxv]

Explain

I tried to record my machine using Arch Linux with hyprland (that uses Wayland) but when I click the record button, I don't get any response at first click, and at the second click, it crashes with this error:

thread 'main' panicked at src/main.rs:516:46:
already borrowed: BorrowMutError
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

My machine

OS: Arch Linux
Linux kernel: 6.6.36-1-lts
Window manager: Hyprland

I don't think Hyprland support XDG Desktop Portal

Can verify from arch and hyprland. Tried today

Yes it does.

With blue-recorder, when I press "Record" button, XDG-Desktop-Portal window will popup, asking me which monitor to capture. But at the same time, blue recorder will crash, so selecting monitor will not have any effect.

Here is the stacktrace:

thread 'main' panicked at src/wayland_record.rs:119:26:
