Part Number: AM3354
We are using an external LCD with 18 bits (6+6+6) colour connected (24 bits internal), without OpenGL enabled the data signals change state only in sync with the Pixel clock PCLK.
When we enable OpenGL ES 2.0 by running Qt 5.6 we get a distorted data signals on the two lsb of all three colours.
Below an example to make it clear : when I draw a blue (RGB 0,0,255) box in Qt on a black background (REG 0,0,0)
The 4 msb lines are good (top trace B2), only change twice on every horizontal line.
The 2 lsb lines (B0 + B1) continuously toggle, it seems even like they are the inversion of each other.
Is this a known issue of OpenGL, can we disable this feature ?
Kind regards,
Steve
