During my edits I noticed that occasionally the canvas would be detected and directly used as thumbnail. I’m guessing this is some timing issue that depends on the load of the server running headless Chrome?
The thumbnail daemon tries to wait until the page has loaded and is idle, yes.
WebGL is unfortunately somewhat unreliable on our current headless Chrome renderer. We’d like to overhaul our process for generating screenshots with something that is both more reliable, offers higher fidelity, and allows the author more control over the result, but I can’t say yet when that will happen.
on a related note: is there a runtime notebook API we could use to create a grid view of a collection of notebook thumbnails in notebooks that just have links to other notebooks on some subject until Collections feature is available for everyone?
All I am looking for is given a notebook url, get notebook title, preview thumbnail img url, created/update date, author, and number of likes to gen a nice looking notebook list or grid view.
Specific use case: I’d like to create one ‘landing page’ notebook for the Chicago Crimes EDA I’ve done with Apache Arrow data and various charting and mapping libs to showcase my work with one link I can send to prospect clients that looks similar to:
