Safari inverts webpages
Since the update, occasionally I have a problem where Safari will flip webpages upside down.
It's not a clean flip, instead I'll start to scroll, then there will be some running images at the top and bottom, then as I move the cursor around the webpage, pieces of it will invert top to bottom.
I can't reproduce it at will, sadly.
It's the darndest thing I've ever seen software do.
I have to quit Safari and restart to make it go away.
Any ideas?
