This kind of issue.. you mean a visual glitch with limited scope and available work arounds in a more than decade old video game?
Yes, what a serious issue. /s
They are not incorrect that there is a certain turnkey nature of using Intel, and certain merits to using a core that has been basically only incrementally refined for the last 10 years.
And yes, Intel has processor errata too, but AMD had to work through some major ones because it was a brand new architecture. They also chose not to take corrective action for some rather major ones - the fix for the segfault bug should have been disabling uop cache, or to do a recall, instead they just let people go on thinking the intermittent crashes they experience (including in windows) are software-related. They entirely declined to patch the Ryzen Take-A-Way bug, which leaks metadata about page table layouts and breaks KASLR on their processors, leaving users even more vulnerable to spectre v2. etc.
