Last update issue with LCD

Hello.... I was using nanodlp an older version that don't have the 3D AAA so,  I decided to update my nanodlp to last version. After the installation the LCD doesn't work anymore. The lines are offset from the border or sometimes the lines appear completely mess. How can I do to fix it? I want to continue with this release because of 3D AAA....


My LCD is ls055r1sx03
Raspberry Pi 3B+
Nanodlp 4271

I was using this config before the update: (this config doesn´t work with new update)
# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
