Go programs freeze when they are launhed via a Steam client

[hajimehoshi]

Hi,

We've found that a program written in Go language freezes when this is launched from a Steam client. Apparently `gameoverlayrenderer64`s `OverlayD3D3` does a trick which doesn't match with the Go runtime. This happens even when the Go program is just a console application.

Here is the details: https://github.com/golang/go/issues/71242

My Steam client version is 1733265492.

Thanks,

As a workaround, specifying `-ldflags="-X=runtime.godebugDefault=asyncpreemptoff=1"` works.
