> Affects Versions: Apache Flex 4.9.0

> Hi there,
> I'm developing a learning mobile app for children using Apache Flex and so
> far it is going great. Performance is good too. I didnt just learn a lot, but
> i also discovered many problem, one of them is v important and i'd appreciate
> if you guys take a look into it and fix it.
> Problem is related to MultiDPIBitmapSource. It is working fine , however when
> i pass MultiDPIBitmapSource to a bitmapImage/Image controls with fillMode =
> repeat, it scales the image twice (instead of just replacing the image with
> appropriate dpi which is a usual case)
> To generate the bug, simply pass a MultiDPIBitmapSource to any image control
> with fillmode = repeat,
> Waiting for reply, Thanks
