Description tomcb 2012-06-05 10:34:20 UTC
Problem description: When highlighting is toggled on, moving the mouse to the top or bottom of the writing window causes the page to scroll really fast. This is really irritating, as it means that as soon as you move the mouse back to the document from the toolbar, the page scrolls upwards, and you lose your place. For some reason it will scroll to the start of the document upwards, but only to the end of the current page downwards. In case compatibility with my touchpad is the issue, it is made by synaptics.

Steps to reproduce:
1. Toggle highlighting 'on' at toolbar
2. Move mouse to either top or bottom of writing window.

Current behavior: Page scrolls in direction that mouse is placed.

Expected behavior: No scrolling automatically.

Platform (if different from the browser): Windows 7 64-bit.

I noticed that when you are in the position that header is invisible in the viewing window of your document and turn on the highlighting, then while moving mouse back to document area text is scrolled downward automatically. Also the behavior is inconsistent: when in highlight mode sometimes I can scroll downward and upward without problems by just moving the cursor, but sometimes it will scroll only to beginning or ending of the active page, sometimes it will scroll just few pages up/down or one up, few down or vice versa.
All this is very annoying.

P.S.
I am using plain mouse.

Breaks text selection as well as highlighting.
Comment 6 konsultor 2016-03-18 20:49:20 UTC
Fast scrolling still a problem when highlighting is on, in LibreOffice 5.0.4.2 (from openSuse).  Without highlighting, the scroll is slower but still too fast (for me).
Testing in OL document IG4202 (chapter on slide masters) I find that I can't scroll with the mouse across the page break between pages 9 and 10.

A possible solution to this problem or a similar one (jittery, inconsistent scrolling through page breaks), is uncheck everything except hardware acceleration in "Graphics output" found in Tools > Options > LibreOffice > View.

Scrolling in these settings is smooth as silk on Windows 10 pc. It is probably a bug between the NVIDIA GeForce GTX series (mine is the 960M) and OpenGL.

Still happening.

LibreOffice 6.0.4.2 (x64). Build ID ID de compilação: 9b0d9b32d5dcda91d2f1a96dc04c645c450872bf.
Windows 10 64bit.

Please make an option to disable completely the automatic scroll when highlighting is toggled on.
I need to highlight hundreds of pages every day, and this feature slows me down a lot.

does not display this problem.  Scrolling with the mouse cursor seem much smoother and crosses page breaks without hesitation.
