Grid showing with snap shot

When actioning a snap shot shot I get a grid showing in part of the image. Is there a way to stop this.
Attached is a computer screen shot showing the workspace before the screen shot, then the what is rendered by the snap shot.

my settings are set not to show the grid.

Running Moi 5 Beta.

Thanks
