Load the attached script using the open folder button in the toolbar
Run the script using the play button in the toolbar
In the resource tree, double click the script named GraphicsBug, to open the script in the script editor
Click Save-Sync-Run in the script editor
I see the script editor maximize after run.
When I minimize it the graphics windows are gone. I tried tiling to see if they have been moved off screen, but that does not bring them back.
