@dreampiggy Sorry for my misunderstanding, this is occurred on the latest.

@d-date Seems works on the iPhone simulator. Does this cause issue on the real device ? Because libwebp for ARMv64 device using the NEON optimization. Where the iPhone Simulator is x86 device. I guess maybe it's related to this.

I will find a real device running iOS 12.0 beta firstlly.

@dreampiggy Yes, I've checked on my iPhoneX and also happened.

This is run on my iPhone X.

@d-date Did you try the 5.x branch for this as well ? It seems I need some time to get a extra test iPhone and upgrade to iOS 12... 😅

@dreampiggy 5.x branch works well for me!

Simulator:

Physical Device (iPhone X):

@d-date Conformed seems a bug that because of using the wrong arg in CGImageCreate. However, this seems does not cause issue in the previous iOS release 😅

It also happend on the iPhone Simulator. Sorry that I previous using the 5.x branch for testing but not the master branch. 5.x branch using another bitmapInfo for a little performance consideration, so it does not cause this issue.

See #2348

@d-date You can test the master branch now. It should been fixed.

@dreampiggy LGTM😎I tested on Simulator and my iPhone X and works well! Thank you for your great job!
