macOS

I'm on Mac OS sonoma beta and I've been using the solar gradients wallpaper since it exists. But a few days ago white vertical bars appeared on the wallpaper. When I switched to another wallpaper and switched back the white bars disappear. Yesterday the same issue happened, but when I switch back to the solar gradients wallpaper, the vertical bars are still there. Although any other wallpaper doesn't show vertical bars, I really want the solar gradients wallpaper back, how do I fix this?
