I have created a custom conky showing weather forecasts in 3 cities like this:

But recently I've begun to see a strange behavior. After a few seconds, a white background a bit larger appears underneath like this:

I've attempted to overcome this by trying a number of changes in the configuration file .conkyrc and the only effective one was changing own_window_type value from override to normal. But then I not only have this conky disappear when I choose to minimize all windows, but it also displays a transparent background of the same size like this:

My conky window settings are like this:

update_interval 1

total_run_times 0

cpu_avg_samples 1

net_avg_samples 1

no_buffers yes

${image ~/.conky/base.png -p 0,0 -s 300x480}

Can somebody tell what might be causing (and how can I overcome) this unwanted canvas underneath my conky window?
