I've just closed the upstream ticket with these comments: It's become clear that this problem is related to VirtualBox. It seems to affect users who are running a version of VirtualBox that can proxy USB events on the host to a virtual machine (the open source version of VirtualBox does not do this). As such, it's not a Shotwell bug. Marking as wontfix.
If anyone sees this behavior who does have VirtualBox installed, feel free to reopen. -- Shotwell makes USB mouse jumpy/jerky https://bugs.launchpad.net/bugs/555408 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
