@miniksa basically while (true) puts("hi");

I also tested it with std::cout, and also WriteConsole directly.

OK. Sometimes they back-end on different functions on our side. I'll whip up a little utility and try this out. Thanks.

Hmmm, not happening for me on 17686. Let me go stand up a 16299 image and see if it happens.

Doesn't repro on my machine anymore (10.0.17134.112)

The code was

#include <stdio.h>

int main()
{
    while (1)
    {
        printf("hi");
    }
}
