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!
