De temps en temps "Afficher l'incrustation" n'est pas sélectionnable

Bonjour,

Lors de la création d'un masque il arrive parfois que la case "afficher l'incrustation" n'est pas accessible et que la visualisation du masque n'est pas possible.

Quand cela arrive c'est toujours avant tout réglage : dès qu'un ajustement est fait sur le masque la case redevient accessible et le masque visible.

Google translation: "Occasionally "Show Overlay" not selectable.  When creating a mask, it sometimes happens that the "display overlay" box is not accessible and that viewing the mask is not possible. When this happens, it is always before any adjustment: as soon as an adjustment is made to the mask, the box becomes accessible again and the mask visible."

Try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.

Thank you John.
Something is not quite clear for me resseting preferences file: what exactely is lost?
Besides, when I restart Lightroom the behavior of display overlay box gets back to normal... So it could be some memory issue, I don't know.

When the preferences file gets corrupted, LR can start behaving unpredictably, with all sorts of intermittent, flaky behavior.  There are dozens and dozens of posts here about all different kinds of problems being fixed by resetting the preferences.  Unfortunately, there is no definitive pattern as to which things are fixed by resetting and which aren't, so we end up recommending trying it in many circumstances in which it turns out that resetting doesn't have any impact.

See the article I linked to above.

It's tedious to get LR back to the way you like it after resetting preferences.  But the article explains how to make a backup copy of your preferences and restore it if resetting doesn't help.  If resetting does help, then you can choose whether you want to fix the flaky behavior or live with it.
