screenshot = nuke.executeInMainThreadWithResult(QtGui.QPixmap.grabWidget, widget) No, didn’t work. Tried to combine that, like you suggested, with processEvents. Still getting a white rectangle.
I’ve created a ticket <https://supportportal.thefoundry.co.uk/hc/requests/15762> with The Foundry and will hopefully get some kind of clever ideas on why this might be happening.
