Text shows as white box when zoomed out?

Hello,

It seems like some text gets white boxes and is not displayed, this is probably normal as the object is being determined 'too small' for display.

But is there any setting to change this? I would like it to display these "small" objects.

As you see in the screenshot attached this is how it looks from my normal unzoomed view, the white box replaces the '3' but the '4' is displayed.
If I were to add another number or letter to the text it would display.

Greatly appreciated if anyone has a tip for tweaking this so it displays the text.
