Pedal lines disappear while adjusting a frame size

Hi, I am experiencing some strange bug in Engraving mode. Pedal line disappear while I am adjusting a frame size. Did I miss something?

As I saved this project, closed and opened it, pedal lines are there again. It seams to be some graphic bug there…

Yes, it came up before, still happens sometimes when adjusting staves etc.

Thank you for your answer. I didn’t find this post before. If somebody of Dorico team would like to take a look, here is a project attached. To reproduce this issue, please do an action showed in a gif example before.

Thanks for attaching the project. We have fixed this bug and it will not occur in the next release.

Thank you Daniel:)
