Hi X547. Yes, that is known issue related to how the dirty views get notified by the AppServer. There is a view stack (TimelineView, TimelineEdit, TimelinePosition), and only the topmost layer gets notified (which in this case is the TimelinePosition) but the lower layers are not notified. I cannot invalidate a lower layer from TimelinePosition since it causes corruption. I've left solving this challenge for another time since the user can quickly "fix" the issue by clicking on the TimelineView if they're actually using the app (the corruption happens when the user is moving another window over the Medo window). The fix may be as simple as attaching TimelineEdit as a child of TimelinePosition, I'll investigate that after the holidays. Thank you for taking the time to report the issue. Happy holidays.
