Comment 6 for bug 1325987

Likely this is a problem upstream of Lubuntu.

I am running Kubuntu 14.04, updated as of 09/09/2014 (kernel: 3.13.0-35-generic) and also experiencing this problem at least both in Thunderbird and Chromium.

When the machine is under load and the GUI is lagging keystrokes are shuffled, missed or even transformed into others: it even happened to me that by keeping backspace pressed in the Thunderbird search bar I was getting random keystrokes being input into the latter searchbar.

Should I open a bug on kubuntu-meta or this bug can be reassigned to an upstream package?
