CAS UI is low resolution

I'm playing The Sims 2 Legacy Collection at 1920x1080 and I noticed that the UI in CAS is low-res and a bit blurry. It wasn't the case in the Ultimate Collection so I thought I'd report it. While it may not be as clearly visible in the screenshot, I can guarantee that it can be seen in game, especially compared to the Ultimate Collection. That being said, the UI in live mode/build mode and in the neighborhood view isn't low-res, it's only that way in CAS.
