Description

Expected behavior: Recording a video using the GUI and <lockstep>true</lockstep> should work.
Actual behavior: When <lockstep> is true then the GUI deadlocks.

Steps to reproduce

Modify the video_record_dbl_pendulum.sdf example world to set <lockstep>true</lockstep>
Run the world.
Select the video record button.

Instead of clicking on the button on the top left, if you load the Video Recording plugin from the plugin menu and start recording, the deadlock doesn't happen.

I would kindly like to confirm if there has been any resolution to the issue with the top-left button causing a deadlock and if any progress has been made on addressing it.

As far as I know, it hasn't been addressed.
