It seems that the customer application is not properly working on Linux with Wayland. If the customer application is running on Fedora 29 (latest version), the staff only receives a black screenshot.
It might be an issue with OpenJDK. Or maybe there might be a way to explicitly allow an application to take screenshots. Fortunately Wayland is currently not widely used. But sooner or later we need to find a solution.
