Wonderful work with the library! But I have a problem likes shown below:

problem1

problem2

problem3

I have a Raspbian O.S.

Does anyone know why this happens?

These are the parameters that I used:

sudo ./demo --led-rows=16 --led-cols=32 --led-chain=1 --led-row-addr-type=2 --led-multiplexing=3 --led-brightness=20 --led-gpio-mapping=regular --led-pwm-bits=11 --led-scan-mode=0 --led-pwm-lsb-nanoseconds=500 -D 1 runtext16.ppm --led-slowdown-gpio=2

Thanks!
