Hi everyone,

I am developing i.MX6 product. When I checked Qt5 APP by using SABRE kit, there was short straight lines.

Could you help me?

Hello Coiln,

if issue appears only for 720p and 1080p, this may point to processor

internal buses bandwidth limitation, one can try to decrease fps or change

IPU QoS with i.MX6Q IOMUXC_GPR6, also check About MMDC Profiling Tool for i.MX6 

 Regards

Hi Bio,

When I tried 800x480 (7"), 800x600(12"), 1024x768(15"), there was the same issue.
