Question Misaligned text in build mode but not in scene/game view

Hey,

I'm trying to display some UI elements in unity with ASCII. I created a canvas and new text mesh pro text element, copying in the ASCII text, and it displays in both the scene and game view with absolutely no problems. As soon as I click the build button and view my scene that way, one row of the ASCII text gets repeatedly misaligned.

Scene/game view:


Build mode:


Is this just a bug or am I doing something wrong?

Method of repeating:

-Create scene
-Create canvas
- Create new UI text mesh pro element
-Copy in the following ASCII text (a different font may be require to make it look right)

________________
/ _/ ____/ ____/
/ // / / __/
_/ // /___/ /___
/___/\____/_____/

-Observe difference in both scene view and build mode

Thanks,

Dan
