UI text is scrambled in mobile and don't get fixed until updated

Text component in UI gets scrambled for some reason only on mobile. We cant reproduce it in the editor and seems random on mobile. It persists when switching scenes and gets fixed if that field updates. fonts are roboto-bold and something called cartoonist-kooky. the same font may look fine in a scene when a field with the same font may be broken in a different scene.

configs of roboto-bold:
-font size: 16
-rendering mode: smooth
-character: dynamic
-ascent calc: face ascender
-legacy bonds: false
-should round: true
-include font data: true

example of a mild scrambling. sometimes it can be completely illegible:
