A little shift on left for the center screen after a refresh

When I switch on my screen or after a unlock, the default screen is display like the beginning of a move on left. After slide a finger, the default position is come back well.

How many screens you have in your preset? You have the same amount of screens in your preset and in your launcher?

3 screens.

Here the central screen, with normal alignment

Here the central screen after an unlock.

I think my phone was in landscape mode when it was locked, and be in portrait mode when it was unlocked.
