Terrible update performance when grid is enabled

[Shebbe]

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.

Specs:

Win11 R9 5950x / 128GB / RTX3090 566.14 studio driver

4K Sony Footage XAVC MXF

4K 25p comp cached

Grid enabled

Viewer zoom 200%

AE 24.5 & AE 25.2.0b24 beta (slightly faster but still issue in beta)
