I use my custom carrier board with a 4,7" 480x272 LCD display, connected via parallel 18bit RGB interface.
vidargs passed to kernel:
video=mxcfb0:dev=lcd,EDT-480x272,if=RGB666 video=mxcfb1:off fbmem=16M
For graphic output testing, i use the Qt demo:
Qt5_CinematicExperience --platform eglfs
With the module placed on the Colibri Evaluation Board V3.2, the demo is displayed on a VGA monitor without any errors.
But with the same module connected to my custom carrier board, I get color artifacts / outlines around all (animated) objects:
Even the tux on the startup-screen has some colored pixels around it:
Seems like a problem on rendering semitransparent outlines ob overlaying objects…
Ethernet, USB and RTC are missing on the custom carrier board. Do you have any idea about the reason for those rendering / blending errors?
