DSI Video Mode: Shifted Image Occasionnally

I'm driving a customized LCD with STM32F469IIT6. However the image was shifted occasionnally. This issue is very hard to reproduce as it occurs 3time max a day. I'm pretty sure that the sync configs are correct. I noticed that the lane byte clock is close to its limit. Is there any advises or instructions ti solve this? I can give you more details about the issue.

Hello @123scy321 ,

Do you mean the whole framebuffer is shifted? Also does it ever get back to the original position?
