My DJI P4 drifts when hovering. Can it be a bent prop? Any idea?

Are you in P mode? Because if you're flying ATT mode, this is normal, no GPS lock in ATT. But, if your'e flying in P mode, and you see that it doesn't stay at the same spot, you might need to do a proper Compass calibration!

How far does it drift..  A few inches of 'wandering' is OK, especially if there's a wind.   I'm assuming you're in P or S mode...  It will drift in Atti because the GPS is turned off.

Does it drift horizontally or vertically, or both?

There should be no drifting above the specs, if there is then preform an IMU calibration.
You should not have any bent propellers. And if you have had even the slightest accident like a small tip over to where even one prop scraped the ground you should discard that prop and install a new one. Any kind of prop strike, you should install new ones.Can you please post a video showin gthe drifting.
Hover Accuracy        Vertical:
+/- 0.1 m (when Vision Positioning is active) or +/-0.5 m
Horizontal:
+/- 0.3 m (when Vision Positioning is active) or +/-1.5 m

Ok  calibrated the compass  And still drifting. Pull back and drifts  forward few feet in  "P". I have single sign with a red line on top?

Have you calibrated the IMU as well? In your picture, there is a communicate problem between your RC and phone. Try to change the cables or replug it.

The picture was after I landed and shut it off

A bent prop should have no effect in P-mode as the quad is supposed to correct anything thanks to the GPS !
