What you did
Rendering a Text2d results in what looks like a uv sampling issue that wraps around, sampling the bottom of the character at the top. This is most noticable on a 1 with Bevy's default font.
It is most noticable on a 1080p monitor, but still occurs on the 4k that I have, just less often.
Here is a video of my slowly resizing the window, rendering a 1 (it's minesweeper, so many 1s). The issue occurs at specific window sizes.

Additional information
I unfortunately don't seem to be able to reliably reproduce this. In certain configurations of window size + application run it is very clear and in others it just doesn't seem to happen. I am not doing anything especially interesting other than spawning a text2d with the default settings.
Scaling mode on the camera is ScalingMode::AutoMin
