Lightroom Classic CC grainy photos when developing
So I've just decided to upgrade to lightroom Classic. Probably should have waited. All of my photos now have an unnatural (non added effect or from high ISO) amount of grain or banding in them as what it used to look like in the old Lightroom CC when the photo was loading. Now what happens is I'll switch to a photo and it'll be fine for about 2 seconds then the banding/noise appears. Fortunately is doesn't follow along when exporting the file. Here's a screen shot of what I'm seeing. The top part is what is being rendered in Lightroom Classic and the bottom half is the same section of the photo zoomed in slightly more with no banding/noise. This needs to be fixed asap. Any help is greatly appreciated.
