Turning on VT Streaming Removed Texture

Having a sudden issue in UE5.2. Never happened previously but now all of my textures (sRBG on or off) that have Virtual Texture Streaming on blur/remove texture. Weird there’s still a color, makes me thing there is some sort of resolution issue so we are seeing a single color in the image.

Vid of issue:

Any guidance on what could have changed?

I changed Tile size to 128 and it seemed to fix the issue (looks like its the default setting). I don’t understand yet why it worked (or how it changed).
