The device I'm testing with (an adafruit 1.8" tft LCD) didn't work properly unless power cycled. This looks to be caused by the reset signal being too short. https://www.displayfuture.com/Display/datasheet/controller/ST7735.pdf This datasheet says that the reset should be at least 10 milliseconds.
Also, I'm not sure if setting the reset line high before low is required.
