Hello Jaap-Jan,

The dev team implemented a fix for this issue. If passing testing the fix will be included in the R3 2021 official release- expected mid September.

Hi Didi,

Sure, I just hope it is also possible to update to a 2.x version of SkiaSharp. :)

Hi Jaap-Jan,

Yes correct, on Android MIUI the latest SkiaSharp version 2.80.3 seems to help in this case.

I can assure you that the issue with the mouse-wheel scrolling is escalated to the development team and I cannot promise but I hope the fix will be included in the R3 2021 official release expected mid September 2021. The item status will be updated accordingly. I hope the time frame is suitable for you? If I have more details on this case I will let you know.

Fair enough, but then the Android 'all pages are grey' bug is back.

The only solution then would be to include a different version of SkiaSharp for Android and UWP, which is far from ideal.

Workaround:

Until the issue is fixed -> Use SkiaSharp 1.68.0. With this version the exception cannot be reproduced and you can scroll through the document using mouse-wheel.
