Description of problem: After typing a search term in the location bar and pressing enter, search results come up. If you move your mouse wheel down one tick, you should see that the page does not scroll. From the second tick onward, there is no issue with scrolling. Version-Release number of selected component (if applicable): 38.0, in Fedora 22 only (not in Fedora 20 or 21) How reproducible: 100% Steps to Reproduce: 1.type a search term in the location bar and press enter (doesn't seem to matter which search provider you're using; tested with Yahoo and a customized Google URL) 2.move mouse wheel down one tick Actual results: Does not scroll Expected results: Should scroll slightly Additional info: Happens in other circumstances, too, such as navigating by hyperlinks between pages, but I was able to get the most consistent results following the steps listed above.
Which desktop environment are you using? I'm having this problem with Firefox on Fedora 22, but only in KDE Plasma, not in Gnome. I'm wondering if our issues are related.
I'm using the Mate Desktop environment.
Same problem in Xfce and LXDE, too.
Yes, I can see that too.
I can reproduce that also in Epiphany and i3wm.
It seems to be problem with GdkEventScroll struct. The delta_y is set to 0 while direction is GDK_SCROLL_SMOOTH so Firefox or any other GTK3 app don't know the scroll direction In the next scroll event delta_y is 1 or -1 (depending on user's movement). I'm using mouse without free scrolling, only stepped movement. I'm going to recheck in Gnome.
I have reported a very similar problem against gtk3 here: https://bugzilla.gnome.org/show_bug.cgi?id=750994 I believe it could be the same core issue.
Moving to gtk3 as long as it is relevant to all GTK3 apps.
I updated to gtk3-3.16.6, and it seems this bug is fixed. https://admin.fedoraproject.org/updates/gtk3-3.16.6-1.fc22?_csrf_token=7cdb4a62f7dd4ac5b9f005f0c88522e6805d7515
I no longer experience this issue with gtk3 3.16.5-1 and Firefox 39.0-8
Please read the upstream report. It was fixed, but the fix will be reverted and the devs currently don't know how to fix it in a different way.
This bug is back in gtk3 3.16.6-1 :-(

Still valid in F24.
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '24'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 24 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
