I think I found a shadow bug that affects all recent github versions that we can try with DXR in 2019.3 alphas, including active code work done in recent days: Raytraced shadows break in play mode if more than one object in the scene is set to static. They look fine if looking at game view when play mode is not activated. They look fine if there are no gameobjects set to static, or if only 1 is set to static. When more than one static object exists, shadows are still being drawn but in totally the wrong place/from the wrong angles. I mostly tested using shadows from a directional light, using HDRP/staging with 2019.3a12. I've had the issue before, but back then I had not figured out what caused it to show itself or not.
