Fill Color Pick Lagging Out

My Fill Color Picker in Substance Painter starts lagging badly after a few minutes of use. I’ve already tried running the app as Administrator and even reinstalling it, but the issue persists. The lag makes it difficult to change colors smoothly. Any suggestions on how to fix this?

AMD Ryzen 7 5800X3D
