I'm using sabayon for a few months now, and lately my Konsole started to display a strange behaviour.
Every time I try to scroll the screen up, all writing get messed up. If I do it with page up and page down, the problem does not happen, but if I scroll using shift+up or by going in the up arrow, it happens.
Here are images of the problem: http://img840.imageshack.us/i/befores.png/ http://img84.imageshack.us/i/afterxw.png/
It does not matter if I alternate windows and get back, once the problem happens, it only gets "normal" again by doing scroll up and down.
I tried to do equo libtest, and it gave me no errors. I have no more ideas. I'm running Konsole 2.5.4 and KDE 4.5.4.
