Strange image in between normal images #24

Hi, I am using vimba ros driver for my project with Vimba G-917C color camera. I have recently observed that sometimes I get weird images in between normal ones. I am not able to figure out the reason for this. Has anyone else also experienced the same?

Does it happen with another viewer or node?

Sorry for the late response. It seems that this is an issue with the CPU not able to process the packets fast enough. I was using an Intel NUC board for processing. The issue arises only when compressed_image topic is being subscribed to which means compression of the raw image is taking place, a CPU intensive task. I observed CPU usage to go near to 100% and occurrence of this weird image becomes more frequent. One solution for me was to lower the FPS which seems fine to me.
