Soft and jagged looking icons and text in Sonoma.

I have a 2009 Mac Pro, firmware flashed to a 5,1 - 2x X5690, 64GB ram, 8 GB RX580, plus a lot of other hardware, 3.1 USB x 4, Titan Ridge Card, 1TB NVme for Sonoma. I have Sonoma running well but it’s showing icons and text on the screen looking very average. I haven’t got the same issue if I boot into Windows 11 or Monterey. Anyone know how to fix this?
