Text cursor misbehaving in Access text field, what causes this and how do I fix it?

Steps to reproduce: create a data-bound form with textboxes showing text field values. Place the cursor in a textbox. Type.

In my Microsoft Access 2016 accdb, I have a form with textboxes showing table field values. When I click on any of these text boxes, the blinking text input cursor appears in the text box more or less as expected, but with an offset that grows as it moves further to the right.

What I mean by offset is that the cursor is shown in a certain place, but entering/deleting text happens a bit further to the left. With the cursor all the way at the beginning of the textbox, editing happens right there. But at the other extreme, if I hit End, the cursor is shown some 5-10% behind the text in the field. Moving a position to the left with the left cursor key, the cursor is still some distance behind the displayed text, but entering text happens before the final character. And when I click somewhere in the middle of the text, the cursor can even display in the middle of a character, and editing always happens a bit to the left of the cursor.

It's as if the text is scaled at 95% for display, relative to the (invisible) text for cursor positioning.

Interestingly, I took a look in my tables, and the behaviour in text fields in the tables is exactly the same.

I've found reports of this elsewhere, but none of the causes and solutions apply here. There are no special characters (tabs or otherwise) in these text fields. There is no code in the Change event. There is no timer running.

I suspect it's a scaling issue somehow, but I can't find any explanations or solutions anywhere. And the issue makes editing the text data near-impossible. I've resorted to copying the text to Notepad, editing there, and pasting it back.
