So I have just done another quick test to run fluxbox instead of kde
with no kde/qt software running. After some time the same problem
arised, so it is unrelated to kde.

Also, rarely but this issue has happened on the keyboard as well... I
try to type something and I don't see anything in the current window
but my text is in another window...

This is really getting annoying and I have no clue at all what to do...

If you had any idea that would be great...

Thanks,
John
