seems every time the program goes to the line, it cause memory leak, for example, in lala-bar, when I open the launch surface, I do not know why it always no keymap, but it does every time enter this line, and cause memory leak. I have thought it may leak from multi window, but seems only the windows that have keyboard focus that leak the memory,

OwnedFd should drop itself, and close the file. I do not think it will leak... I do not understand..
