Choppy Minimize or Maximize on External Display

Quick Update:

It appears that changing the Minimize Windows Using from Genie Effect to Scale Effect resolves the problem. I don't mind Scale Effect, so I'll keep it that way if it means the problem is resolved.

Looks like it's a bug in High Sierra with an external monitor and Genie Effect that causes Windowserver to suck up a ton of CPU resources. Considering the other problems many others on this forum have complained with High Sierra, Windowserver, the switch to Metal2, and external monitors, I'm going to chalk it up to poor quality control with High Sierra.

So far High Sierra has been the Windows Vista of Apple's operating system releases. Hopefully they'll get it together.

The article linked does not apply to my problem. Actually, in absolutely no place in that article is there any reference to the problem I've written above.

You've told me to Contact Apple Support, which I may decide to do. In the meantime, I'll leave my question here so others who may be experiencing the problem can offer their advice and/or support.

I appreciate that you volunteer your time on these forums, but to be honest I'd rather have no response than a form letter which requires me to write this exact response telling you that your form letter does not at all apply to my specific problem.

I will certainly be fine waiting for someone to offer their useful experience in helping me solve the problem. I'm on these forums enough helping out other people with their problems that I'm certain I'll eventually get someone who says, "Hey, I've got that issue as well, turns out you have to delete the dock prefs .plist and run this command in the terminal".

I'm fine waiting for a resolution. What I'm aggravated with is this form letter I see posted on so many discussion posts on this Apple community website. She gave me a link that had nothing to do with my problem, and even admitted so. Her link asks if everything is updated, what to do if there's fuzzy images, or no image, contrast or color issues, or USB-C issues. I was very clear with my specific problem and the is absolutely nothing in my original post that references anything in the post she linked. I would be curious if you could look at those steps posted in the article and let me know specifically which of those steps I should try to even begin to resolve my issue.

Then she gave me the generic information for Apple Support, which may be a route I eventually go down.

When I see that form letter, it feels like I'm having a problem with my Bluetooth audio stuttering after I synch it to my Chevy's radio, and the response from Chevy is to make sure that there's gas in my car and the electrical system works when I turn the ignition key, and failing that I should just "call Chevrolet".
