Hi,

I am using mac version and I have annoying issue with trackpad.
I use qcad primary with my trackpad and under application preferences (Graphics View/Navigation), my setting is as follows.
Mouse wheel / two finger swipe: Scroll (Trackpad...
Enable pan gesture : unticked (found that enabling this often goes into pan mode when I am just moving my pointer around)
Limit zoom and scroll to prevent overflows : ticked (hoping that this would prevent weird zooming issue. I will describe what I am experiencing later this page)
Reverse mouse wheel direction for zoom :unticked
Mouse wheel zoom factor: 1.02

Things work as expected:

  • panning with two finger swipe
  • and the rest

Issue I am experiencing:

Often, when I am zooming in and out with two finger gestures, the view suddenly sets to some weird state and my drawing goes off the ruler.
The mouse point remains where it is.

Workaround:
Reset viewpoint with autozoom and navigate around.

Expected zoom behaviour:
I expect viewpoint to zoom in / out at where my mouse pointer is or at least the centre of current view point.

This task depends upon
