• So the problem persist, time to time... I suppose spi is asynchronous...
    Therfore I've added a reboot() at the end of each cycle (all text done and led cycle done)
    The spi is reinitialized and every thing look good. And there is no messe on the display.
    I suppose i can do in an other way by adding more time to the first line, it seems, it's at a restart (when substring displayed (my cursor) go back to beginning) which the prob issue.

    Thanks for your help.
