Something I noticed and reported as a bug in-game is some glitchy face textures on Zenos. I did get the reply that the bug report would be elevated for further review, but here's some examples if other people wanted to check if it's the same on their end.

Hidden for spoilers, and long row of screenshots:

- Stormblood lv. 60 quest "Where Men Go as One" cutscene #2, shows a red ear


- Shadowbringers lv. 78 quest "A Breath of Respite" cutscene #2, shows a red ear


- Post-Shadowbringers lv. 80 quest "Reflections in Crystal" cutscene #5, shows a red ear and pixellated shading on skin


- Endwalker lv 83 quest "In from the Cold" cutscene #2, shows a red ear and grid-like pixellation of face shading


- Endwalker lv 83 quest "The Martyr" cutscene #6, shows pixellated shading on skin
