Text Blur on Overview Screen search results

Using Zorin 18. I'm getting very blurry text in search results in the overview screen. See image. Same in Wayland and X11. Blur my shell is OFF. Otherwise, text in app windows is normal. Font is Liberation Sans 12 Regular. No font scaling used. I tried other fonts and they were all affected. Any ideas how to clear this up? [overview-text-blur]
