sokol_app.h: Linux mouse-click event coordinates incorrect without prior mouse-move

[legends2k]

Once the app window loads, without moving the mouse, I simply click the primary button. I get an event callback:

void event(const sapp_event* ev, void* data) {
  switch (ev->type) {
    case SAPP_EVENTTYPE_MOUSE_UP:
      std::cout << "Mouse up: " << ev->mouse_x << ", " << ev->mouse_y << '\n';
      break;
    case SAPP_EVENTTYPE_MOUSE_MOVE:
      std::cout << "Mouse move: " << ev->mouse_x << ", " << ev->mouse_y << '\n';
      break;
  }
}

Prints

Mouse up: 0, 0

This is incorrect since the cursor is truly at around (200, 100). If I ever-so-slightly move the mouse and click, I get

Mouse move: 200, 100
Mouse up: 200, 101

I.e. the right coordinates.

No bug on Windows; not sure about macOS (don't have a device).

Hmm yeah, that's indeed an inconsistency and should be fixed so that it behaves the same between platforms. Thanks for filing an issue!

PS: on macOS and Emscripten it appears to work as expected, both from the touchpad and with a mouse attached, so it looks like it's only Linux which behaves differently.

Ok, should be fixed now, the mouse position is now also updated for non-move events.

Validated! Thanks for fixing this :)
