Description

10 years ago
I see this issue on:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b3pre) Gecko/20090123 Shiretoko/3.1b3pre

i'm on a long bugzilla list of bugs, i scroll up or down with the mouse wheel or the keyboard up/down keys (does not happen if i drag it to a position). The grippy appears and disappears intermittently.
Notice this does not happen on short pages, seem to happen only when the scrollbar grippy is at minimum size.

i recorded a small video to show the issue:
http://www.bonardo.net/scrollbar/

I'm not sure this is the right component for scrollbars, but couldn't find a better one :\
If these are native-drawn scrollbars, then it's probably the native theme code, although not definitely.

works:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b1pre) Gecko/20080917034815 Minefield/3.1b1pre
does not work:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b1pre) Gecko/20080918073230 Minefield/3.1b1pre

regwindow could be:
http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2008-09-17+03%3A48%3A15&enddate=2008-09-18+07%3A32%3A30
not sure I've seen this, but I've encountered page which wouldn't scroll using XP Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2a1pre) Gecko/20090621 Minefield/3.6a1pre (.NET CLR 3.5.30729)
20160502172042  Mozilla/5.0 (Windows NT 6.0; rv:46.0) Gecko/20100101 Firefox/46.0
20160509040557 	Mozilla/5.0 (Windows NT 6.0; rv:49.0) Gecko/20100101 Firefox/49.0


I tested on Windows Vista x86 with FF latest release 46.0 and latest Nightly 49.0 on a long bugzilla list of bugs and I can't reproduce the issue.
Please retest this on the latest Firefox version and see if you can reproduce the problem.
