Just bumped into a new problem with 2 boxes running 1.22.1 on Mandrake 10.1/10.2.
If you adjust the source-settings, for example change fps settings, the "live view" opened by clicking the monitor name in the console view shows the picture in 4x size. Quite uncomfortable

I thought I messed up with the first box but I was able to replicate the problem with another box up and running.
