Flickering and banding happening in shadows/texture all over the game

There is flickering and severe banding happening in the shadows/textures all over the game since patch 7.2. I have seen this happening on environment objects like in the images provided, around character hairlines and necklines, in cutscenes on player characters and NPCs (easy to find example for NPCs is Sphene and Krile in the Backroom in 7.2 MSQ), on mounts, on housing objects (especially outside). etc. It is happening all over.

It can be dependent on the lighting, in-game time of day, weather, light source, and direction of the light source. For example, the sand dune issue disappeared after 3 PM Eorzea Time and onward into the evening, but the issue returned, though much more subtle, around 6:20 PM Eorzean Time. (Clear Skies weather both times it was observed at this time).

(happening along top edge of the sand dune, very subtle)

Date & Time: Since 3/25/2025 - Patch 7.2
Frequency: All of the time
World name: All worlds
Character name: All characters
Area and coordinates: All locations in the game. Emphasizing, this is happening ALL OVER the game in various places. For this specific one Southern Thanalan ( 21.3 , 30.8 ) Z: 0.3

Steps:
1. Be anywhere in the game
2. Look around at various shadows and how they are interacting on objects.
3. Find objects with flickering/banding/"marching ants" type shadows. Seems to be especially bad with larger contrast in lighting/overhead lighting, but it happens at night where shadows meet a lighter object as well.
4. Observe the flickering and strange banding happening in the shadows. The example provided is the most egregious example I've been able to find where a screenshot shows the problem without needing to take a video.
