I honestly vastly prefer using IDA and Windows specific tools (x64dbg) over gdb. IDA can interface with gdb so it can act as a frontend which can be handy for visualization.
I tested with OCCT to find even more errors, so either do that in a mini windows environment or do one of the Linux tests to check memory some more. Memtest86+ isn't enough.
It kind of still is because of Webview2. Games such as Forza Motorsport (not that you'd want to play that crap) depend on it for Xbox login purposes even if you bought the game on Steam. The game depends on the system Edge libraries and doesn't ship its own.
As for most board vendors nowadays, I think they barely do anything with the code itself and just create the setup utility and boot logos. It is highly likely that they're affected too.
Hey Shadow, what do you think of this guy's cock?
