@megan-phet please add assignees and labels to bug reports or else they may be missed. If you are unsure about either, please ask @KatieWoe.

Otherwise, @megan-phet are there any errors in the console when this happens? May be helpful.

@phet-steele It sounded like @megan-phet was having trouble adding assignments and tags for some reason. I've been looking in to see what the cause might be, but haven't found anything yet. Thanks for adding them. Correction: It looks like she doesn't have write access in this repo because it's not listed in the QA group.

I see, thanks for finding that out! Sorry @megan-phet.

https://github.com/phetsims/blackbody-spectrum/issues/65 additional details in duplicate issue. (I initially thought it was a new issue on iPads).

Significant lag also occurs. This issue also seems to occur during the last few zoom ins (can occur at 0.00007, or at least large amounts of lag) and most of the high temperatures.

The blackout portion of this issue seems solved when testing Mac 10.14 safari in the new dev version. @arnabp

Since blackout issue appears to be fixed, I'm closing. I will note however, that general performance issues will continue to be observed and fixed on a general basis.
