Hey @Hong, Thanks for using the dev forum! Would you be able to provide a video of the issue? Also we have released a new version that fixes various issues in that version, can you please update? Thanks! Michael ---

Thank you very much for your reply. Yes, will try to capture the video clips to show you. It only happens when I call PIN functions but not spotlight Function. I think it must be something to do with the video frame buffer for the pin function. I noticed that the first 5 participants are fine, but the 6th and beyond, there is always a short black screen in front of the video. Since I am looping the PIN function when it reaches the end of the list, I noticed the symptoms repeated itself. Hope that would helps. ---

Hi Michael, It still behaves the same with new release zooo-sdk-windows-v5.7.6.1072. When I tested with a small group say only 5 or 6 participants no black screen issue. But when I run in the actual meeting with around 20 participants , the black screen appears between videos starting around the video of the 6th participant. The cycles repeat when it loops around. Consistently. Hope that helps. I got the video clip to show you but do not know how upload. Hong ---
