Apple has finally fixed a display problem with its new iMac: AMD’s 5700XT graphics card refuses to backwash

spent tens of thousands of dollars to buy the iMac, shows that the problem is getting worse, apple obviously cannot ignore, of course, this is not the quality of AMD graphics card.

Apple today released an update to macOS Catalina 10.15.7, which fixed a problem with macOS that didn’t automatically connect to wi-fi. It also fixed a bug that caused files to fail to sync via iCloud Drive.

Of course, for new iMac users, it fixed a problem that caused white lines on the screen of the machine with the Radeon Pro 5700 XT.

users have been complaining about graphics glitches since the launch of the 27-inch iMac in August, which includes a higher-end 5700 XT GPU. Many users reported seeing a flicker of horizontal white lines, and while it wasn’t clear whether it was a software or hardware problem, today’s fix shows that it was indeed a software-related error.

Before that, a number of users of the 2020 iMac had posted on apple’s official support forums that their computers were experiencing a display glitch, with random white lines appearing on the screen. All the 2020 imacs in question had AMD Radeon Pro 5700XT graphics, the highest option for the 2020 iMac.

according to some users, the first thought was that the iMac was overheated due to work and the lines appeared. It turns out that white lines still appear randomly without any action. After a variety of CPU and GPU run points and tests, everything seems to be normal, but the problem is still random.
