Yesterday, Apple released a new support document . It describes a problem where the right side of the Mac screen may flicker or distort when running on Windows 10.
This happens with AMD Radeon graphics. On external displays, distortion appears across the screen.
The company does not yet have a clear solution to the problem. However, a couple still offer: upgrade the video card driver, or reduce the resolution on third-party monitors. However, the latter option is not suitable for Apple Pro Display XDR, as well as LG UltraFine 4K and 5K. [ MacRumors ]
