http://bugzilla.suse.com/show_bug.cgi?id=1053959 http://bugzilla.suse.com/show_bug.cgi?id=1053959#c9 --- Comment #9 from Jiri Slaby <jslaby@suse.com> --- Quoting from https://bugzilla.mozilla.org/show_bug.cgi?id=1390795#c1 We explicitly keep MOZ_USE_XINPUT2 off by default because behaviour is buggy when it is turned on. The code is at http://searchfox.org/mozilla-central/rev/13148faaa91a1c823a7d68563d9995480e7... and references a couple of bugs. From the discussion in those bugs it's still not clear to me whether this needs to be fixed in Firefox or elsewhere. Some of the comments seem to imply it affects other apps as well, not just Firefox, which would make it a GTK issue most likely. But I'm not sure. -- You are receiving this mail because: You are on the CC list for the bug.
