Strange display issue in large, constant area chart in boost mode

I was going to post this as an issue on github, but I'm having trouble fully recreating my issue in jsfiddle so I thought to post it here for more of a discussion basis. I would have waited till I was able to recreate, but I feel stuck and would love any input on the issue.

Expected Behavior

When displaying a large, nearly constant area chart in boost mode, it should display as a large rectangle with no visual discrepancies in the area below.

Actual Behavior

As shown below, the area underneath the large, mainly constant piece of data displays with strange lines underneath it. This only happens when in boost mode. I need to use boost mode however due to the scale and amount of large graphs I'm plotting. Not using boost mode makes the app almost unusable.

using Highcharts 10.2.0

Below is the live demo that I have put a dataset that has shown the above issues. I was not able to recreate the issue I am having, but wanted to provide you with what the data used actually looks like.

Hello and welcome to our forum and thanks for contacting us with your question!
I was not able to recreate the issue I am having
You did not import the boost module, so it did not start at all.

In this case you need to use boost.useGPUTranslations.
Here you can read more about this: https://www.highcharts.com/docs/advance ... ost-module
