Export to PDF leaves charts empty on first export

ignasv commented 3 months ago

Bug description

When using the new Export to PDF functionality, we get a mostly empty PDF on the first try. Second export usually works fine. If we refresh the page - same issues reappear: first export is empty, second is fine.

The issue does not seem to impact Big Number and Table charts. But everything else: Pie Charts, Bar Charts, Area Charts, seem to be impacted.

How to reproduce the bug

Open a dashboard which has a Pie Chart.
Click Export to PDF
Check PDF

Same issue for me, with the 4.0.1 version of superset.

I also face exact same issue (4.0.1)

Same problem, but worst:

For me it only prints what is visible on the screen. Anything outside it is not printed, but rather shows the Superset loading logo.

Is this using the webdriver component? If yes, perhaps it is not waiting long enough to take the screenshot.

@hanslemm i think this is the issue. I don't know which technology they use to generate the pdf. But it may be just a option to force the rendering of all the page and not only the visible part.
