I have this issue with ESDR2 and Colibri Nano. Every now and then (lets say after 5-10-15 minutes of starting Colibi Nano), without me doing anything. the screen changes to something like the attached picture. Sometimes it is not completely red just green or yellow, but anyway, I have to drag the vertical scale to the left of the spectrum scope to put things right or even stop/start the device. But after another 5-10-15 minutes scope scaling will jump again.
Is it something unique to my computer, or does anyone else experience this?
