Attached is a quick patch that inspects that valuator accesses do not go out of bounds. I changed only the motion and button accesses and not the Wacom one. The reason being that it seems to loop over all data so it should be valid.
I have not tested the patch in any way, so it might not even compile. I have not tried replacing system Qt ever so I reckon someone with more experience ought to try it first. As far as the sporadical thing goes, the situation for me is the reverse: I don't get any errors for pressure but I do get it for tilt. Since my tablet does not seem to support tilt, its values should always be zero. There's also the case that I get different behavior on evemu-traces than the real tablet. Xorg log does say I am using Wacom input module. ** Patch added: "valuator-range.diff" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+attachment/2425854/+files/valuator-range.diff -- 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/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+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
