Issue with dcc.Download

[AIMPED]

Hey all,

Kaleido and windows are a bad combination. There are some threads about this. Downgrading to an older version of kaleido helps sometimes, see also

Writing an image taking too long

I had a similar issue in windows 11. Had to downgrade to kaleido==0.1.0.post1. However, if you’re trying to convert big data to static image (in my case to avoid slow interactive charts), there is a hard limit. In one of my plots, a scatter overlayed with density distribution scatter plus marginal violins, the input table can’t have > ~1.8e6 rows. Apparently, that is fixed in latest kaleido version, but latest kaleido hangs in W11 during image conversion (last time I checked).
