LiteOS 5 Graphic error Radeon 3

[chriswp]

Dear all,
I just upgrade from version 4 to 5, but something wrong happened in my display. When login all the thing in monitor was scrambled.


I tried to boot into recovery mode, then resume to normal mode everything is good. But when rebooted into normal mode the abnormal display was still there.
Please tell me what I have to do to fix this issue. 


This is my test command result:
