I am running X-Plane 11.26 on a multiple monitor setup (three monitors, 45 degree FOV per monitor). The rain effects are not correct. Rain on the left monitor appears correct (nearly horizontal streaks, as you'd expect). The rain on the right monitor falls vertically, as if the aircraft is parked. I think LR needs to check that rain and snow effects align properly across multiple monitors (minor issue but noticable especially on night IFR approaches).
