Terrible update performance when grid is enabled

I was doing some compositing and wanted to scrub through a cached shot while the grid was enabled to see some alignments. I noticed that the whole application stutterd and only updated at about 5fps. 

It improves if you zoom the viewer to fit, but zooming to 200% is terrible.

I think it's really concerning that a simple grid overlay causes such issues and I hope this can be adressed very soon.
