record a file menu from blender

[vince_br549]

I have been creating blender tutorials with OBS on Linux. I can't find a way to capture all of blender except with XHSM. I want to be able to capture the blender application AND the file selector and import/export windows. If the blender file window is open, I can grab it and capture using Xcomposit. That grabs the file selection window, but as soon as the file selection window is gone it grabs the entire blender window and I end up with two complete sets of the main blender window.

Same issue with import and export windows.

I see suggestions for using game capture, but that ain't on my Fedora 33 ( the latest ) version of Linux.
