#15039 closed defect (fixed)

[patch] prevent zoom level from jumping after click on slider

Reported by: ar2988-os@… Owned by: team
Priority: normal Milestone: 17.12
Component: Core Version: tested
Keywords: template_report regression zoom Cc:


What steps will reproduce the problem?

  1. Load some OSM data
  2. Zoom out by a factor of 8 or more using the scroll wheel. Note that the zoom slider does not move.
  3. Drag the zoom slider

What is the expected result?

The zoom level changes one step at a time

What happens instead?

The zoom jumps back to where it was before step 2

Please provide any additional information below. Attach a screenshot if possible.

This is a regression since (probably) r11826 or r12039. The zoom slider used to move when zooming with the scroll wheel.

The same problem arises after using the various View > Zoom to... functions (shortcuts 1 to 6, 8 and 9).
