Canon EOS RP High Speed Sync

[mistromel97]

Hi new owner of a Canon EOS RP. Recently upgraded from a Canon 6D. I've been researching and testing out hss on the RP. Although, post firmware version, top banding has been fixed but I still see striped banding across the image at shutter speeds 1/1000th and above. Is there a workaround for this? I'm using the Godox flash system: Xpro-C for the trigger, 2 AD200s and an off-brand speedlite with the X1R-C as a receiver for the speedlite.

Does the exact same external flash setup work on the 6D without the striped banding? 

Please show us an example of the striped banding.  Could it be a from CFL or LED lighting?
