I'm having a really weird issue on my Mac Pro and I'm very worried about my pictures in iCloud since the library is now repairing and stating it is uploading... A lot of my recent pictures are shown with this corruption on the right side or down side of the picture depending on the orientation: What I figured out so far in the last half an hour: No other screen / image glitches occur It only seems to impact the pictures taken with my iPhone 8 Plus with the back camera in HEIC format. It does not show on the front side pictures which are also in HEIC format. The HEIC preview in Finder (after airdropping directly from my phone to my Mac Pro) shows the same weird stripes but as soon as you open it in Preview the corruption isn't visible anymore. When exporting (dragging) pictures to my desktop the corruption is gone (converted in JPG automatically). Everything above is not the case on my MBPr 15" Late 2013 in Photos and also not on my iPhone only on my Mac Pro. The previews in the library show correctly only when opening the pictures you can see this corruption. I hope it's some driver issue of the GTX 680, I'll try the latest Nvidia webdriver next since I'm using the included MacOS driver now... Edit: No Nvidia Web Driver is available so I'm stuck with the included default graphics driver. Any suggestions or similar experiences would calm me down.
