Have just upgraded from 19.11.1 which was fine to 19.11.2
Fortnite Save The world has badly corrupted textures on My Sapphire Vega 64 Nitro+
its fine on My Sapphire R9 290 Tri-x so is Vega Codepath Specific
not sure about Navi/Polaris..
Rolling back to 19.11.1 Fixes it
Also Tried ddu then fresh 19.11.2 also the same
So rolling back again..
Have uploaded a recording here
