I've made guides out of a large number of lines (forming an iso grid). This works fine as long as I am viewing the guides as lines, but when changing the view to Dots in settings, Illustrator get so slow that I can't even move around in the document. I am using Windows 10 version 26.1. I also have v25.4.1 installed and it is the same thing there.

Maybe it would be less performance demanding if we could set transparancy on guides instead of using dots?
