add_softcursor() stores the contents of the text buffer position in this variable before drawing the softcursor, whereas hide_softcursor() writes the value back. A value of -1 means that no cursor has been drawn and therefore no character is to be restored. softcursor_original, however, is only implicitly initialized with 0. Therefore, when hide_softcursor is called for the first time (console_init -> con_init -> redraw_screen -> hide_cursor), it wrongly writes 0x0000 in the top left corner of the text buffer. Normally, this is just as black as the rest of the screen (vc_video_erase_char) and can't be seen, but it appears as a black cursor rectangle on non-black backgrounds e.g. with boot option "vt.global_cursor_default=0 vt.color=0xf0". softcursor_original needs to be initialized with -1.
