Martin Gerhardy Not sure - but I think there might be a logic flaw in SDL_SetWindowGrab. The problem here is that this modifies the window flags and e.g. sets SDL_WINDOW_INPUT_GRABBED - but the _this->grabbed_window pointer is not yet set. Then in SDL_UpdateWindowGrab the _this->grabbed_window pointer is only set if the function pointer _this->SetWindowGrab is not NULL. But if this is NULL, the _this->grabbed_window pointer is never set, but every future call to any of the grab functions include an assert for: SDL_assert(!_this->grabbed_window || ((_this->grabbed_window->flags & SDL_WINDOW_INPUT_GRABBED) != 0)); That means the first call works, the second always fails and triggers the assert. |
