What does a grille on the sun line mean?
What this means
First confirm the mark is a small mesh of several crossing lines, not one cross or one horizontal bar.
A light grille can suggest temporary distraction or mixed feedback, while a dense grille may point to stronger stop-start visibility.
Check whether the sun line clears above the grille, and compare nearby islands, cuts, the fate line, head line and both hands.
