70% of the times I used to use Illustrator CC 2017 my cursor used to flicker extremely fast switching from the tool I have selected to the default black pointer. With CC 2018 looks like it's 100% of the times.
It's very annoying especially when I have to make accurate selections.

I can reproduce it in Illustrator 24.3 still! It really sucks. Working with 5k screens and a flickering cursor. so annoying...
How much longer will we have to deal with this super annoying and distracting problem? My patience has tapped out after at least 2 years of dealing with it.
Same here, it's really annoying.
