   Measured 2026-10-11 (10.5x, still pointer, F9 toggles, 3840x2160):

   • Wind writes the same transform in both states (txTrace). Inspect always shows Wind's centre; free mode shows DWM centring, which sits 1 desktop px off in x (±11 screen px, either sign), 0 in y. None at 1.8x.
   • The offset comes from Wind's moving pixel-and-back nudges. With every zoomed nudge removed, DWM matches Wind's centre exactly (0 shift, 9/9 runs). With any moving nudge kept (all, split across ticks, or only the per-write one), the 1 px offset is back.
   • A zero-distance SendInput move is dropped by Windows (no event), so it is the same as no nudge.
   • Without nudges the magnified pointer still shows during and after a keyboard zoom (55/55 ramp frames), but panning shakes the pointer up to 30 px (167/596 frames vs 0). So the per-write nudge has to stay.

   Open: no clean fix found yet; options in the session.

   Closing as is (2026-10-11). Entering Inspect no longer shifts the view (#446). Leaving Inspect can still shift the view by DWM's 1 desktop px offset until the first hand movement; the measurements and the remaining idea (hide the pointer without swapping cursor images) are in the comments above.
