SDL_SetWindowPosition does not set position when using wayland video driver

[madebr]

The py-sdl2 test_SDL_GetSetWindowPosition test fails when running with sdl2-compat, and using the wayland video driver.

Equivalent C code:

#define SDL_ASSERT_LEVEL 3
#include <SDL2/SDL.h>

int main(int argc, char *argv[]) {
    (void) argc;
    (void) argv;

    SDL_SetHintWithPriority(SDL_HINT_VIDEODRIVER, "wayland", SDL_HINT_OVERRIDE);
    SDL_setenv("SDL_ASSERT", "ignore", 0);
    int result = SDL_Init(SDL_INIT_VIDEO);
    SDL_assert(result == 0);
    SDL_Window *window = SDL_CreateWindow("hello", 10, 200, 10, 10, 0);
    SDL_assert(window != NULL);
    SDL_assert(SDL_strcmp("wayland", SDL_GetCurrentVideoDriver()) == 0);

    int px, py;
    SDL_GetWindowPosition(window, &px, &py);
    SDL_assert(px == 10);
    SDL_assert(py == 200);

    SDL_SetWindowPosition(window, 0, 150);
    SDL_PumpEvents();

    SDL_GetWindowPosition(window, &px, &py);
    SDL_assert(px == 0);
    SDL_assert(py == 150);

    SDL_SetWindowPosition(window, 480, 320);
    SDL_PumpEvents();

    SDL_GetWindowPosition(window, &px, &py);
    SDL_assert(px == 480);
    SDL_assert(py == 320);

    SDL_DestroyWindow(window);
    SDL_Quit();
    return 0;
}

SDL2 output is empty.

sdl2-compat output is:

WARN:

  'px == 0'

WARN:

[Kontrabant]

You can't programmatically position windows on Wayland. The SDL automated tests skip the positioning tests when the video driver is "wayland" for this reason.
