Having done some digging, I've found at least one reliable way to
reproduce the issue with -Q:

1. launch Emacs using `emacs -Q';
2. switch to *scratch* if not there already;
3. do M-x column-number-mode RET;
4. paste the following Persian text into *scratch*:

   ویکی‌پدیا دانشنامه‌ای اینترنتی با بیش از ۲۸۰ زبان با محتوای آزاد است که با همکاری افراد داوطلب نوشته می‌شود و هر کس که به اینترنت دسترسی داشته باشد می‌تواند مقاله‌های آن را ویرایش کند.

   It is from the first sentence of the "دربارهٔ ویکی‌پدیا" (About
   Wikipedia) section on <https://fa.wikipedia.org>.

   The text should appear garbled.  However, if you omit step 3, the
   pasted text should appear just fine.  It appears that if Persian text
   is pasted before column-number-mode is enabled, even if the paste is
   subsequently undone before enabling column-number-mode, the issue
   does *not* surface.

The above works for pasting into a message-mode buffer as well.  I have
not tried to find a recipe specific to gnus-article-mode yet.

Hope this helps.

P.S. if I did not mention earlier, all of this is on a Debian Buster
GNU/Linux system.
