Thanks for reporting.
Just to understand this better.

Did you set refresh to 500ms with refresh=500?
What is the frequency of the flickering?

Even removing the refresh or the conditional activation doesn't cause a change:

Frame label="WCAM01" {
		Image item=WCAM01_Image refresh=500 visibility=[WCAM01Activation==ON]
		Switch item=WCAM01Activation label="Kamera" icon="camera"
		Switch item=WCAM01_GoToPreset icon="movecontrol" label="Winkel[]" mappings=[9="Standby",6="Default",7="Wohnen",8="Kochen"] visibility=[WCAM01Activation==ON]
	}

	Frame label="WCAM02" {
		Image item=SurveillanceProxy_SurveillanceProxy_WCAM02_Image refresh=500 visibility=[WCAM01Activation==ON]
	}
}

I have the same problem here ...

Persistence is rrd4j, i.e. data ist stored in .rrd files and images are also generated via rrd4j.

Images like the following are flickering, even when refresh=0 ist set.

Image url="http://localhost:8080/rrdchart.png?items=iEG_XX_RTR_TEMP_IST,iEG_YY_RTR_TEMP_IST,iEG_ZZ_RTR_TEMP_IST&period=h" visibility=[iDummyChartIntervall_RTR==1] refresh=0

This seems to be triggered regularly all 30s - no matter what.
