Dockerized usage results in non-specific error

[MangledPotat0]

Hi, I am trying to integrate screen capture using scap into a GUI application I am developing inside a docker container. I am working scap version 0.0.8 because that's the latest one that isn't in beta.

During instantiation of Capturer, I keep running into the following error:

thread 'main' panicked at /usr/local/cargo/registry/src/index.crates.io-1949cf8c6b5b557f/scap-0.0.8/src/capturer/engine/linux/mod.rs:334:14:
Failed to get screencast stream: LinCapError { msg: "The user interaction was ended in some other way" }

but it doesn't specify what the problem is so I am not sure what I need to try. My host machine is running X11 (KDE). I have matching UID/GID for the user between the host machine and the docker instance. I have set up bind mounting to share the dbus session and display device. When I comment out the code for scap, the GUI appears normally so I don't think it's resource sharing issue between host and container unless there's something specific to scap that I am not accounting for.

Included below is the full stack trace, though I am not sure how useful this is going to be. If anyone has any suggestion on what may be going wrong, please let me know. Thanks in advance.
