Problems With the Radeon Pro 5700 XT with 16GB or 8GB of GDDR6 Memory With the 2020 27" iMac?

[pacificm]

I'm interested in purchasing a 2020 27 inch iMac. However, I've read many entries in Google of people using the Radeon Pro 5700 XT with 16GB of GDDR6 memory graphics card and running into issues with streaking white lines across the screen. People have also had issues with the 8GB version as well. Many entries have reported this problem and say that Apple has not recognized or responded yet to the problem. It sounds as if the problem is persisting with Apple not pursuing a remedy. This has me concerned and hesitant to make a purchase.

Please let me know if you are having any such issues and if they have been resolved or not.

Thank you.
