After using Lightroom Classic for a few weeks, I began having an issue today. Although the images in the Library module were fine, when I opened them in the Develop module I saw a mass of colored streaks throughout the photos. This made it impossible to work with them. I closed LRC, left it alone for an hour, reopened it, and I could work on images again. I closed LRC, left it alone for an hour or so, and the problem returned.  This is affecting both the images I took the other day and some older ones that I had previously imported. See the attached images for a sample of what I see.  I have LRC release 13.2 with camera RAW 16.2, and I'm running it on a 2019 MacBook Pro with an Intel Core i7 processor and AMD Radeon Pro 5300 M graphics chip in addition to the integrated Intel graphics.  Can anyone enlighten me on how to fix this?  ...
