Hello again.
Sorry if I top post the thread, but seems strange I'm the only having this 
issue. It happens with different distros as well as on different boards.
I would exclude OS or hardware problems.
If someone suggest me how to debug, would be good.
A sort of backgroun screen-refresh would be a workaround as well, but don't 
know how.

Many thanks!

Simon
