Hello there ! i'm back again to try RPR, and with 2.8 official and RPR version 2.0.112 i notice a problem with dual video card. I still have here a Radeon Pro DUO Polaris (that Blender see as dual wx7100), and when i use both for preview, everything looks ok at start... but... when i change just a random material valor, the preview is divided as you can see in the image. The left part look like it do less sample.. and this is really annoying. If I turn off one card all work well..
