mirror_y=True in lvgl_esp32.Display

[robmaster2016]

display = lvgl_esp32.Display(
spi=spi,
width=240,
height=240,
swap_xy=False,
mirror_x=False,
mirror_y=True,
invert=True,
bgr=False,
reset=48,
dc=38,
cs=12,
pixel_clock=20_000_000,
)
display.init()

When I activate mirror_y I have graphic glitches. Everything else works.

Best regards
Rob
