Build system: Yocto Poky ( https://github.com/Freescale/meta-fsl-arm)

Linux kernel: 3.10.17_r0

vivante binaries: gpu-viv-bin-mx6q-3.10.17-1.0.2-hfp

Display: 12" (1280x800) LVDS

Board: Custom (based on imx solo)

Vertical white lines interlaced with black and white image is been displayed on the LVDS Screen while running the sample tutorials. The snap of the LCD is attached for the reference. Terminating the tutorial gives the right resolution and the color.

Frame buffer is functioning normally.

mode "1280x800-60"

        # D: 71.098 MHz, H: 49.374 kHz, V: 59.993 Hz

        geometry 1280 800 1280 800 32

        timings 14065 40 40 10 3 80 10

        accel false

        rgba 8/16,8/8,8/0,0/0

endmode

Any help/hint which can help us resolve this issue would be appreciated.

This problem was resolved by passing the correct boot arguments (bpp was corrected)
