The statistics tab in the Inspector for Babylon.js seems to crash

I don’t know in what version this happened, but it seems that Inspector crashes when you select Statistics in Inspector.

Here are the steps to reproduce the issue:

  1. Access the Babylon.js Playground.
  2. Click the “Inspector” icon at the top of the screen.
    → The “Inspector” will appear on the right side of the screen.
  3. Click the “Statistics” tab in the “Inspector”.
    → The “Inspector” crashes and disappears from the screen.

I see. As you point out, this problem only seems to occur in Chrome and Edge. I confirmed that it does not crash in Firefox.

This is why I really care about backward compatibility…

They changed “PressureObserver.supportedSources” to “PressureObserver.knownSources” leading countless websites to crash for freaking no reason…

Will be fixed in a few hours


Thanks for taking a look at this @Deltakosh! For anyone else still getting this, I had to upgrade from BJS 6 to 7.
