Nvidia Shield tablet graphic bug

I’m trying to put our lat archviz scene (just a bathroom) on the brand new shield tablet we got yesterday…I just created a deviceprofile and a new postprocess volume with higher priority and lower quality setting (like bloom at 0, ssr quality really low etc… basically following these guidelines more or less https://docs.unrealengine.com/latest...cts/index.html) …I’m pretty happy with the result cause i’m getting 30 fps and a really good overall quality, all this without optimizing anything at all… the problem is i keep getting these strange bugs at the border of the room and i can’t understand what is causing it…i changed all lights to static, removed bloom,lightshafts and all other effects but nothing changed…only thing that seems to get rid of it is lowering the value for the console variable r.scenecolorformat but makes the scene unplayable causing other visual bugs (basically a tremendous ghosting) so i have to keep it at 4… do any of you know or has any idea on how to fix it? thanks in advance!
