Text scrambled when being changed quickly

Has anyone had any experience with uGUI text getting scrambled when it is being updated quickly? ie: if i have a counter that is changing a text value every frame sometimes (perhaps when the cpu load is high) the text becomes scrambled (like each letter is using the wrong part of a text atlas so you see parts of other letters, or it could be an alien language… not sure which). The scramble only stays for a few frames and then the text returns to normal for a few seconds.

Ran into this on some iOS devices and according to some other thread it was related to Metal combined with dynamic sizing for fonts. The workaround was to create a separate properly sized non-dynamic font for the texts that required to be changing per frame.

Here’s the previous thread:
