Presume you mean the world 0,0,0 axis (see pic).
You can turn off the display of that by turning off the Show FPS in the Settings screen.
You might find trying to record from screen using some screen capture tool will result in poor performance or dropped frames in any case if your PC is so slow.
Note that what you see on screen in Build Mode is not the full quality resolution or application of all effects etc, so the quality you may end up capturing may not do justice to either the scene you are doing or to Lumion.
Have a look before trying screecaps at using lower output quality settings in video render as well as maybe using the Low Memory flag in Settings.
Also, when rendering you have choices of output format, and of course even if it seems slow when rendering the video animation it is producing a final result for you. Nothing is instantaneuos (yet).
