Hello !
I have a XFX rx 5700 xt and i notice that since i bought this card reflections are jagged / blurred.(wet textures, water, shiny textures, yellow and black surface). First i blame faulty drivers, now i'm suspicious that the card might be defective. I install / uninstall using DDU (sometimes i reinstall windows) all drivers versions since the card was released on market until now (the last is 19.9.2) and the reflections problems still persist.
Here is video to understand what i mean :
