how to solve the split screen for lvds+hdmi imx6q

hi,how to solve the split screen for lvds+hdmi,when the video moves,hdmi results split screen,for double framebuffer,how to change kernel file.lvds+HDMI双屏显示时，视频移动，hdmi出现卡屏/裂屏现象，是不是没有双缓冲的原因，对于内核函数ipu_init_channel_buffer可以初始化ipu输入输出通道，双缓冲在那设置的在获取v4L2数据设置，还是在fbmem设置。imx6q  thanks...

what bsp version do you use? pls share the test steps and uboot settings, did you try one display? is it ok for hdmi or lvds separately? only dual display mode has this issue?
