Hello, i use a mx6dl processor running with Yocto Morty. I have gui application running on fb0 and video running on fb1 in a window using imxg2dvideosink. Video is small 240x120 and i use local alpha to uncover only video region of fb1.

No problem up to 1024x600 but when i turn to hdmi at 1920x1080 (video size remains unchanged) i have screen turning off and on for a few times and then it turns off definitivelly after a few minutes. I have following errors:


[ 1568.833307] imx-ipuv3 2400000.ipu: warning: wait for bg sync eof timeout
[ 1572.143078] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x88800000
[ 1572.143089] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000


Already tryed dmfc=3 with no success.The problem is not related to application on fb0 since i can reproduce also by running a video on fb0 and another one (always windowed) on fb1.


Any hint wolud be much appreciated.

Thank you
