Apple has now solved the problem of screen distortion when some Mac is running win10.
Apple released a support document yesterday detailing the possible distortion on the right side of the Mac screen when running Windows at 10:00.
The problem occurs on Mac models with AMD Radeon graphics cards. Part of the Mac screen flashes and distorts on the right side, and on an external monitor, this distortion may affect the entire screen.
In addition, the Windows 10 installer may point out that this Windows 10 version is not supported on Mac computers because of the older AMD graphics driver.
To solve this problem, Apple encourages users to install newer AMD graphics drivers for Windows. When the new version of the driver cannot be resolved, the user can follow the instructions to reduce the resolution when using an external monitor. Apple says this method works for most external monitors, but not for Apple's Pro Display XDR and LG UltraFine 4K and 5K monitors.
