can't see cloud
this is strictly speaking not a problem of spacekit, but I have following issue:
it concerrns https://www.meteorshowers.org/
on a mobile device (Samsung S4 mini with Chrome that is no longer updated) I can perfectly see the meteor cloud (I guess implemented as particles):

on Ubuntu 16 running on an XPS-13 I don't see the cloud:

the planets aren't visible either.
and when I run the example https://typpo.github.io/spacekit/examples/meteor-shower/index.html
I do see planets, and particles:

could it be that there is an issue on https://www.meteorshowers.org/ ?
thx
(I couldn't find contact info on that site.)
ah, this might be interesting:

The same here, but just using Firefox browser, with chrome family, like Vivalde or Chromium, works. Any ideas why just with Firefox dosn't work?
- I tried this again, on Ubuntu 18 this time (and FF 71), same issue.
- On Chromium 79 it DOES work fine
