This problem does not only affect the front camera (IMX681), but also the rear camera (OV13858). This issue is present both in GPU and CPU mode, but the error seems more prominent if the object exits and reappears in the capture zone and while the camera is starting up in the first use, This error is also visible if the GPU is used and if you put an objet close to the camera (for example, a white sheet of paper) ¿Maybe is caused by the ligth the camera recieves? The GPU debayer is still broken but i do not have the knowledge or time to identify the root cause, make a solution, create the report and send it to the corresponding place Tested-by: German Pablo Lindo
