Public bug reported: >From https://bugs.freedesktop.org/show_bug.cgi?id=30068 "XWarpPointer should generate Motion but not RawMotion (it's RAW, right?). And it definitely generates wrong RawMotion, because it contains valuators' values equal to absolute screen coordinates of mouse move target (and that is definitely wrong, since all other mouse events are relative).
So, my point is that XWarpPointer shouldn't generate RawMotion events at all." He also includes a small testcase. Happens in Ubuntu 10.10 and 11.04 (or any Ubuntu with XInput2 support). Affects apps that use xinput2, e.g. wine as of roughly wine-1.3.20 or later. Drives users nuts... the main menu of Bioshock Demo and many other games is nearly completely useless because of the jumping mouse when xinput2 is used; see http://bugs.winehq.org/show_bug.cgi?id=27380 The lead Wine developer, Alexandre Julliard, has been waiting for this bug to be fixed for some time now. He's trying to work around it, without much luck so far. ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/792598 Title: XWarpPointer sends wrong raw mouse input event _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
