If you look at the second video very carefully you can see that the cursor does not jump to the corner when the selection expands.
What probably happens is that the application that does the background selection does not handle XInput valuators properly. An extremely similar bug was fixed in Qt recently. The reason this bug does not happen in Arch is that it does not provide this new XInput data so it uses "classic X" cursor location. To fix this bug we need to find out which app does XFCE desktop selection, how it reads XInput data and fix that. -- 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/832624 Title: cursor jumping to screen border To manage notifications about this bug go to: https://bugs.launchpad.net/unity-foundations/+bug/832624/+subscriptions _______________________________________________ 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
