Description Gabriele Ponzo 2017-02-10 15:17:55 UTC
If you click in the "empty" area of the scroll bar (when visible) it scrolls just 1 pixel per click!

Steps to Reproduce:
1. Open whatever module (Writer, Calc, Impress or Draw)
2. Import an image (to have the SideBar full of sections and thus scrollable)
3. Expand all the sections (by clicking on + on every one)
4. Click on the empty area of the scroll bar

Actual Results:  
It scrolls one pixel per click.

Expected Results:
It should scroll of one graphical page, meaning the exact amount of pixels shown, if available, otherwise to the end of the bar.

Reproducible: Always

User Profile Reset: No

Hmm, confirming 1px scroll on click.

On Windows 8.1 Ent 64-bit en-US with
Version: (x64)
Build ID: 7074905676c47b82bbcfbea1aeefc84afe1c50e1
CPU Threads: 8; OS Version: Windows 6.29; UI Render: default; Layout Engine: new; 
Locale: en-US (en_US); Calc: group

Also, on Windows build the scrollbar has end buttons, clicking those moves the pane 1px-so assume that is intentional.

Click + hold + drag on the "slider" scrolls smoothly. And mouse "wheel" scroll is reasonably smooth at about ~5px increments. Not sure this needs any effort, but lets ask the dev.

@Thomaž, should the scrollbar button widgets or a click move in larger increments? Even adjust increment to match the length of the pane exposed (i.e. length of the gray slider)?
