I had changed the desktop wallpaper. The "window environment" stopped working.
Top and bottom panels disappeared, icons too.
The former wallpaper was still in its place.
All the nautilus windows was not drawed on the inside.
Transmission continued it's own work.
The file transfer window too was not repainted anymore.
After the report was made everything returned to normal function. No data was lost.
