Vuescan preview very slow after 9.8.02

Anyone experiencing this? There were numerous other problems, like the crop area inexplicably being a rectangle even though aspect ratio was locked at 1.

Most of this was fixed in 9.8.03, but the preview speed is still crawling. I’m using a V600, so you may understand this is a drag, as that’s a slow scanner already haha

Any fixes? Or just wait till next update :confused:
