Bug Report: Runaway playhead (SOFIE-2899)

[ianshade]

About me

This bug report is posted on behalf of SuperFly.tv

Observed Behavior

Sometimes the Playhead in the Timeline View goes past the end of the current Part and even past any subsequent Parts. The current Part refuses to visually extend its width. Refreshing the browser tab doesn't solve the issue. Performing a Take usually solves the issue, however then the previous (problematic) part shows as having 0 width.
This happens randomly on various Parts, without clear steps for reproduction.
1:

2:

3: (After taking out of the problematic Part - 6th in the Intro segment, it displays with no duration and a "flag")

Expected Behavior

While playing, the current Part should keep extending its width until another Part is taken, and retain its as-played duration until reset

Version

Release50 and Release51 of Sofie Core, with the Demo Blueprints (https://github.com/SuperFlyTV/sofie-demo-blueprints)

Hello!

Thank you for reporting this bug! If you haven’t already, please give our contribution guidelines a read.

We have arranged with @ianshade to have the snapshots of the system handed over for some initial investigation. We have not observed this issue in our installations, so I can't comment on how this is going to be prioritized.

Not sure if it's related but I'm getting quite a few warnings in the console:
