Bug on emulator and Galaxy SIII i9300

[sebastian-ziegler]

Hi, when the sample app opens in my cellphone (Galaxy SIII - i9300), the upper half keeps white and the other one is displaying correctly, after you swipe to the next page, you look all correctly. This bug happens even when you're swiping up or down, it looks a half correct and the otherone looks white. This happens with the Android Emulator too, I'm compiling with 3.0 and I'm testing it over Android 4.3 on both devices.

There is a way to make the flipview look good in all devices? Thanks

This one is when you open the app:

This one is swipping from page 1 to 0:

Hi, seems to be a bug in the canvas.save()/canvas.restore() system in the skia library. I'm not so expert to find a workaround for your code. If someone can point me on the right way i can implement the WA and fill a pull requests with the edits
