I have a i.mx6d borad, and i transplant Android4.3 system to it,  the display panel is lvds 1024*768 60HZ, it goes very ok when it power on, but after 10minutes, the display screen occur overlays. see the image.   it seems something wrong with the ipu or the ldb driver, so i do modify the ldb drivers but the problem still the same , can anyone give some advise? Very thanks if get answers.

It seems the display output is normal after boot up.

Please double check the connection (cable?) between the display and your board.  Maybe the signals are not stable.
