Description Manuel Vögele 2018-09-19 09:00:09 UTC
Zoming in the print preview with Ctrl+Mouse Wheel can cause the preview to jump to a different page.

Steps to reproduce:
- Create a multi-page document
- Open the print preview
- Scroll to the last page
- Zoom in multiple steps by using Ctrl+Mouse Wheel (zooming just one step won't do)
- Zoom out one step by using Ctrl+Mouse Wheel
-> The preview will jump one page up (and also zoom out at the same time).

I can confirm this behavior.

1) Create a 3 page Writer document.
2) Open print preview.
3) Go to the last page.
4) Zoom and preview settings: single or multiple pages with full page view (e.g. 'fit width and height').
5) Zoom in with mouse wheel and scroll 2 times.
6) Scroll back 1 time.

Expected result:
Nothing than zoom level changes.

Actual result:
Zoom level changes as expected BUT also the view jumps to the previous page.

I only could reproduce it in normal view with multiple pages activated but not in print preview.
