Hmm, that's really weird. I guess that's the folder it fails to write.
Is it running as a different user. What if you change the permissions to

That's by design. It allows you to override names from a template
mixin like inheritance but no runtime cost.

Sorry again, where it reads "sprintf" should be "vsprintf".

Here's the result:

rect2.x = x;
rect2.y = y;
rect2.w = font.width;
I forgot to add that the "RenderText(font,0,0,"FPS:
"~to!string(fps));" was an older version where it wasn't const
char *, but string. And I was using a foreach, so no
null-termination. But that's beyond the point of not using GC.
Yes, I'm aware of the null-termination thing. I might have pasted
code that I already changed.
But I already messed with sformat, and it seems that it does use
the GC. I've put @nogc in RenderText, and the compiler says
sformat uses GC, so I don't know.
But the thing is, I don't want to
