@h.g , I’ve checked with the team, and there is an optimization update for the Layer API (ZM-854825) scheduled for Zoom client version 6.4 that will significantly reduce the duration of the white screen flickering effect. I’ve emphasized the importance of this feature for your use case to the internal team and will keep you updated on any developments. ---

@donte.zoom thanks for the update! Is it just reducing the flickering? Or is it fixing the bug where any image drawn goes away? Reducing the flickering won’t solve the issue if the image still disappears. ---

@donte.zoom hey donte, just wanted to follow up on the above 2 questions: 1. Is it just reducing the flickering? Or is it fixing the bug where any image drawn goes away? Reducing the flickering won’t solve the issue if the image still disappears. 2. When is 6.4 expected to be released? Thank you! ---
