Merci beaucoup de votre soutien; comme vous pouvez le constater, je n'ai pas répondu à deuxième message, pour terminer cette discussion inutile.
What I cannot figure out is whether it is a problem of the driver or Nvidia OpenGL libraries. As far as I remember, installing the driver forces the libraries to be installed. It would be interesting to try installing just the driver (but not the libraries, if that is possible) and to check whether the problem persists.
Perhaps we should file a bug with nvidia: it is possible that developers/packagers of plasma did not notice this bug or weren't able to reproduce it since they do not use Nvidia driver.
