When I tap to click, the cursor moves

Created attachment 580308 [details] x.org log Description of problem: Tap-to-click misbehaves in F17, while it worked fine in F16. I installed F17 from scratch, nothing was kept from previous installation, not even /home. When I tap, the mouse cursor moves, sometimes slightly, sometimes more, which makes it hard to hit the target. Version-Release number of selected component (if applicable): xorg-x11-drv-synaptics-1.5.99-7.20120207git141d92120b How reproducible: Always. Steps to Reproduce: 1.Enable tap to click in gnome's settings 2.Tap on touchpad Actual results: The mouse cursor moves. Expected results: The mouse cursor should not move.
I filed an upstream bug for this here: https://bugs.freedesktop.org/show_bug.cgi?id=49200 with a list of potential options to fix this. It's not scheduled for synaptics 1.6 at this point though You should be able to work around this by increasing the hysteresis values but this will have some effect on small pointer movements too.
The problem has been fixed with an update, but I'm not sure which exactly as I had been using an external mouse. My version current version of xorg-x11-drv-synaptics is: Version :1.5.99.904 Release : 1.fc17
fwiw, the problem is still there, I could reproduce it on 1.6RC3. Something may have changed that you don't trigger it as easily anymore though.
Problem is still present with a thumb-side tap/click on xorg-x11-drv-synaptics-1.7.1-5.fc20.x86_64 (on a 2014 Dell XPS 15 Touch). Can this be re-opened please? It presents a serious usability problem.
Luke: best to file a new bug or at least re-open and assign to a new distribution. I'd didn't see this one because I filter emails for EOL versions. anyway, very late comment: lots of touchpad fixes in synaptics 1.7.6 in F20, so that should've fixed the issue
