beaglebone 240*320 pixel display

Hi All,

We have the a beaglebone with an LCD 240 * 320 pixel display. The display is connected as 16 bit.

When booting windows the display look off all kinds of stripes are in the display. I have been searching through the code and came to this point

common\src\soc\COMMON_TI_V1\COMMON_TI\DSS\LCDCAI\surfmgr_flat.cpp

I changed the stride value in the OMAPFlatSurface::Stride function from

dwStride = m_dwPixelSize * m_dwActualWidth * m_dwHorizScale;

to

dwStride = (((m_dwPixelSize * m_dwWidth) +MIN_STRIDE_RGB -1)/MIN_STRIDE_RGB)*MIN_STRIDE_RGB;

This fixes the alignment for our display but I wonder if there is not a lot easier way. So my question is this really a

bug or should I set something somewhere elso to make the stride value correct?
