Several items missing in iOS 13 #164

KatieWoe commented 5 years ago

For https://github.com/phetsims/QA/issues/427 The icon for the first screen is missing both on the home screen and within the sim on iOS 13. It is there in iOS 12. Image from iOS (3)

KatieWoe commented 5 years ago

Edit: Much larger problem in the sim. The alpha particles don't show up on the second screen, and the close up on the first screen is completely gone.

KatieWoe commented 5 years ago

Occurs in published.

OK thanks @KatieWoe. It sounds like most of the protons and neutrons are missing. They are painted in an atypical way in this sim. For instance, see RutherfordNucleusNode.RutherfordNucleusIcon which uses inner class IconCanvasNode.

jessegreenberg commented 5 years ago

The particles use CanvasNode and the rendering context method drawImage. Wondering if it is related to those. @KatieWoe can you please try one of these other use cases of this to see if things show up as expected?

Molecules in acid-base-solutions look fine to me. Charges look fine in BASE

jessegreenberg commented 5 years ago

Thanks for checking. Points to either something more specific to the sim or something else entirely.

jessegreenberg commented 5 years ago

This is caused by https://github.com/phetsims/sun/issues/526. Being investigated there.

This was patched as part of https://github.com/phetsims/sun/issues/526 and can now be closed.
