(Core :: Widget: Win32, defect)

Description

[akulle12]

When having the Electrolysis feature enabled the amount of pixels scrolled from a single click of the mouse wheel doubles.

Comment 1

[timbugzilla]

This happens for me on win32 trunk builds on Win8.1 x64.

Comment 2

[Loic]

Is it reproducible on Win 7 or others OSes?

I opened my Firefox Developer Edition that uses a different profile than my Nightly and it worked fine. I hope this helps although it's not the Nightly build in which the bug occurs.

[John Doe]

I like e10s, it works really well now but this bug makes it really annoying.

Comment 7

[Andrei Petcu]

Same here. Arch GNU/Linux. How come is this in "UNCONFIRMED" state?

Comment 8

[avada]

I'm experiencing this also, but it's not just e10s that prompts it. I also get double scroll length when I enalble APZ without e10s.
Here are the customizations (copied from bug 1158799):

I have 15 lines set in windows' mousewheel settings.

I have these customizations that affect scrolling in firefox:
user_pref("toolkit.scrollbox.horizontalScrollDistance", 16);
user_pref("toolkit.scrollbox.verticalScrollDistance", 12);
general.smoothScroll.lines.durationMaxMS", 450);
user_pref("general.smoothScroll.lines.durationMinMS", 450);
user_pref("general.smoothScroll.mouseWheel.durationMinMS", 400);
user_pref("general.smoothScroll.pages.durationMaxMS", 385);
user_pref("general.smoothScroll.pages.durationMinMS", 385);

Comment 9

[Kevin Brosnan [Ex-Mozilla]]

Fairly sure that this is a duplicate, duping forward since the other bug is clearer.

For those of you on operating systems other than Windows file a new bug. The solution is platform dependent.

Comment 10

[Kartikaya Gupta (email:[e-mail])]

I think you duped it to the wrong bug.

Late night bugzilla'ing :(
