The problem with displaying frames

Hello everyone I have a problem with displaying frames in penpot. Only the frame that is highlighted with the mouse is shown.

Also, previews are not displayed in drafts.

The version is self hosted. Tell me, what could be the problem?

manifested same issue here. Boards don't show preview when not actively clicked on albeit this has been happening for months.

The problem has been sorted out. In the docker-compose file.The bml variable penpot_public_uri should refer not to localhost, but to the public name.
