Points added with a suppressed attribute form all reuse the first point's geometry (4.3.5) #8088

What is the bug or the crash? What were your expectations and what actually happened?

On a point layer whose attribute form is suppressed after feature creation ("Hide form" in QGIS, featformsuppress=1), only the first added point lands under the crosshair. Every following tap on "+" saves a new feature with exactly the same geometry as the first one, even after panning the map to a different place.

Expected: each tap on "+" adds a point at the current crosshair (or GNSS) position, as it does when the form is shown.

What happens:

• After the first point is added, the digitizing toolbar stays visible with the discard (X), remove vertex (-) and add vertex (+) buttons, as if a vertex were still pending.
• Each further "+" creates a new feature (new fid) with an identical geometry, including Z and M values. On the map it looks like nothing is added, because the points are stacked on top of each other.
• The stale geometry persists across sessions: after uploading changes, re-downloading the project from QFieldCloud and even switching the layer to a different file, the next "+" still reused the coordinates from the previous session. Tapping X resets it, then the problem starts again from the next first point.

With the form shown (featformsuppress=2) everything works as expected: 6 taps, 6 points in 6 different places.

We tested the same project with the layer as Point, PointZ and PointZM: the geometry type makes no difference, only the form suppression does.

Example of features created by panning the map between taps (changesets as received by QFieldCloud):

pk=167  Point ZM (10.00000000000000000 50.00000000000000000 0 0)
pk=168  Point ZM (10.00000000000000000 50.00000000000000000 0 0)
pk=169  Point ZM (10.00000000000000000 50.00000000000000000 0 0)

In the field, with the position locked to GNSS, the duplicates carry the same Z and the same M (GNSS timestamp) as the first point, e.g. 13 features with Point ZM (11.00000000000000000 51.00000000000000000 243.7333984375 1790763359000).

Steps to reproduce the issue

1. In QGIS, create a GeoPackage point layer (Point, PointZ or PointZM) and set Layer Properties > Attributes Form > "Hide form on add feature".
2. Open the project in QField 4.3.5 (we use QFieldCloud, the layer has the "offline editing" cloud action).
3. Select the point layer in the legend and enable digitizing mode.
4. Tap "+": a point is added at the crosshair. The toolbar now shows X, - and +.
5. Pan the map to another place and tap "+" again.
6. A new feature is created, but at the coordinates of the first point (visible in the local changes list and in the uploaded changes).
7. Change the setting to "Show form on add feature" and repeat: each point is placed correctly.

Version

4.3.5 - Danube (471940a v4.3.5)

Operating system name

iOS

Operating system version

27.2

Reinstall QField

• I have a fresh install of the latest QField version, but the problem persists.
• Problem can be reliably reproduced, doesn't happen randomly.
• Problem happens with all files and projects, not only some files or projects.

Additional context

• Projects synced through a self-hosted QFieldCloud (v26.28).
• Our field team has been using the same project template with a suppressed form since August 2026 with almost no duplicates. The problem started at the end of September, so it looks like a regression in the 4.3 series. It may be related to the auto-save / feature creation fixes in QField creates multiple polygons when auto save is enabled  #7953 and Fix yet another feature creation issue with auto-save enabled #7960.
• A second user reported the same behaviour on another device; we have not confirmed their QField version yet.
