I've been experiencing a weird behavior with some applications (e. g. Skype), since I updated my Ubuntu to 13.10 and now to Ubuntu 14.04.
When my computer "freezes" due to high CPU usage and I happen to type something in the application at the same time, the application starts to input the characters I've typed during the freeze randomly. I can type some characters correctly, but it will eventually input the memorized characters, no matter which key I press (even backspace inputs characters!).
For example, if during the freeze I type "abc", the application will receive "abc" as input even if I press the backspace button three times! The "abc" pattern will keep occurring until I restart the application.
My problem is similar to this one: Pressing back space inputs characters
At first I thought it was a problem with Skype specifically, but it is also happening with PyCharm (Python IDE), which made me believe the problem is more generic (although not all applications behave like that, just these two - that I know of).
If someone have an idea of how to fix this problem I would be very grateful :-)
