Upon Further Testing. Edit.
7.64.6125 does have this issue.
7.64.6085 has the issue.
Issue does not appear in 7.64.5829.
I'm also unable to reproduce TECO's issue.
Edition: Windows 10 Home
Installed on: 6/13/2020
OS Build: 19042.870
Experience: Windows Feature Experience Pack 12.2212.551.0
Edit 2: I forgot to open multiple windows on the earlier betas, but upon doing so, I did reproduce the issue, unlike when I first made my post, hence the first edit. This edit is for clarity. Multiple windows quickly reproduced the problem, except for 5829, which worked like normal. I even tried a clean mirc.ini as well as my normal ini to compare. Issue persists in both instances. Also updated the windows information to be more precise.
