Created attachment 3230 [details]
a minimal C program that reproduces the bug

Good morning.

On macOS 10.13.4, while trying to do:
```
SDL_SetHint(SDL_HINT_RENDER_DRIVER, "metal");
```

I find that nothing is displayed on the window at launch. I need to resize the window at least once before anything starts showing. Note that everything works as expected with the default OpenGL driver.

Also, another little thing, I noticed that the `SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "0");` setting is not taken into account (also when using metal driver): it always displays graphics as if the scale quality was set to 1 (linear filtering).

I attached a little C program that reproduces the bug: try to resize the window + comment/uncomment the `SDL_SetHint(SDL_HINT_RENDER_DRIVER, "metal");` line).

Thank you for your time,
Best regards
