SDL2.0.5 - SDL_KEYDOWN shows two identicle presses when only one key is pressed

Question

SDL2.0.4 using this code:

SDL_Keycode key = 0;

while(SDL_PollEvent(&(Global->event)) != 0)
{
    if(Global->event.type == SDL_QUIT)
    {
        /* Allow users to exit the game */
        break;
    }
    else if(Global->event.type == SDL_KEYDOWN)
    {
        /* Actual Keypresses */
        key = Global->event.key.keysym.sym;

        if(key == getSDLKValue("p-key"))
        {
            /* ... p key is pressed */
        }
        else if(key == getSDLKValue("q-key"))
        {
            /* ... q key is pressed*/
        }
    }
}

Works fine to get a single p key press when the key is pressed down. However, when manually compiling, and using 2.0.5 logging shows that a single key press has:

Key pressed: 112
Key pressed: 112

It gets pressed twice in the window, when only once in reality.

Is this a bug with SDL2.0.5? Running on Ubuntu 16.04, manually compiled SDL2.0.5.

Answer 1

event.key.repeat is 0 for actual key presses, and 1 for fake presses (which are generated if you hold a button long enough).

To fix this issue, this question suggests to just check if event.key.repeat == 0.

It's possible that 2.0.5 behaves in the way described to make it easier to separately handle text and non-text input.
