I got an error in my tmux session that was effecting my work flow in vim as well as just general konsole sessions while search apt, or whatever. I thought I would share the solution in case some one ran into the problem.
Basically they made a trivial change, probably a micro level change that really bothered a programmer and their pet project. Totally understandable, but it is just too bad I didn't hear about it and it is hard to track these things down. I suppose I will make more of an effort to check up on these things when upgrading to the next LTS. Right now I went from Kubuntu 14.04 to Kubuntu 16.04.
Any way lets get to it. Simply change :
set -g mode-mouse on
set -g mouse on
Now you will have the ability to scroll with the trackpad, or mouse if on a desktop. This should only effect users coming from a version less then 2.1, since that is when the change took effect.
