Do you see an "HD" button in the top right of the image, and does that fix it for you? It might be the data saving settings
I don't think there is a way to combine crossposts yet

No. Unfortunately not. But it seems to disappear, when i uncheck Settings > Appearance > Cards > Full height images. For some reason, i can now enable the same setting again, without that the milky images comes back. On the other hand, it doesn't change the height of the images.
