[Touch-packages] [Bug 1607240] Re: Xmir Firefox scrolling is too fast (mouse wheel) when run under Unity8 (since Xmir 2:1.18.4-1ubuntu4)
Found the solution! System Settings > Mouse & Touchpad > Slide the second (unlabelled) slider all the way left, and then one notch right. Turns out that unlabelled slider is the wheel scroll speed. Setting it one notch from the left correctly reduces the wheel speed from 7.0 to 1.0 as Mir clients expect. ** Also affects: ubuntu-system-settings (Ubuntu) Importance: Undecided Status: New ** Summary changed: - Xmir Firefox scrolling is too fast (mouse wheel) when run under Unity8 (since Xmir 2:1.18.4-1ubuntu4) + Unity8 default mouse wheel speed is 7.0 (it should be 1.0) ** Changed in: ubuntu-system-settings (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1607240 Title: Unity8 default mouse wheel speed is 7.0 (it should be 1.0) Status in qtmir package in Ubuntu: Confirmed Status in ubuntu-system-settings package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Invalid Bug description: Ubuntu 16.10 + proposed Xmir 2:1.18.4-1ubuntu4 wheel mouse scrolling is too fast, tried with firefox and geany. run firefox on mir scroll up/down some random long page using the mouse wheel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtmir/+bug/1607240/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

Confirmed the wheel vscroll value received by Xmir is exactly 7.0: vscroll = mir_pointer_event_axis_value(pev, mir_pointer_axis_vscroll); So for each mouse wheel tick: USC sends a vscroll value of +1/-1 to Unity8 Unity8 sends a vscroll value of +7/-7 to apps In previous versions of Xmir, we would ignore the magnitude and convert the 7 into 1. But now Xmir does proper smooth scrolling we need to honour the magnitude. So a value of 7 from Unity8 now results in 7x more scrolling. The Xmir change is correct and we need to fix some Untiy8/Qt code somewhere so that a mouse wheel tick is always vscroll=1.0. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1607240 Title: Xmir Firefox scrolling is too fast (mouse wheel) when run under Unity8 (since Xmir 2:1.18.4-1ubuntu4) Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Invalid Bug description: Ubuntu 16.10 + proposed Xmir 2:1.18.4-1ubuntu4 wheel mouse scrolling is too fast, tried with firefox and geany. run firefox on mir scroll up/down some random long page using the mouse wheel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtmir/+bug/1607240/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp

Good news: Confirmed I can reproduce the bug. Bad news: The bug only happens in Unity8 and not in Mir demo servers. What changed: Xmir 2:1.18.4-1ubuntu4 adds accurate vscroll/touchpad support. So instead of synthesising vscroll changes of any magnitude into fake button 4/5 press/releases, it now passes the vscroll float value straight down to the app. This works well in Mir demo servers (with high-resolution touchpads too), but in Unity8 Xmir ends up sending about 7 button 4/5 events per mouse wheel tick. It appears the flaw is in Qt/Unity8 code where a vscroll value of 1.0 (which means one mouse wheel tick) is not correctly maintaining the vscroll value of 1.0 after it passes through Unity8. So the Xmir change is correct, but this is at least the third Unity8/Qt scrolling bug I've seen today.
