If the question is related to the free wpDiscuz plugin it doesn't matter if you're a paid customer or not. 

For further support just note: 

• Paid add-ons are being supported here. 
• The free wpDiscuz plugin is being supported on the wpDiscuz.com forum. 

Also - We have been paying customer for years.  We just recently purchased your full "wpDiscuz Addons Bundle". We thought the paid support forum would have higher priority response for paying customers.

Since we pay yearly for your full wpDiscuz bundle, I assumed we should post our questions in this paid support forum?

This comes from the active theme. Please watch this video to better understand what we mean: https://www.screencast.com/t/yXp9IehM

It adds the border: 3px solid var(--base-color); CSS rule for the .comment div. 

You can use the CSS code below to remove it: 

.comment {
    border: none;
}

I may also suggest you reduce the value of the padding CSS property:

.comment {
     padding: 0px;
}

We need a toggle setting to enable/disable and remove those borders around the comments in the screenshot above.

Could you please show the issue on a screenshot? 

The new boxes around the comments makes it really difficult to read them, especially when there are a lot of different comments in one thread, especially when reading on a phone screen.

Is there an option to toggle this new border on/off?
