Earlier this month (September 8 to be exact), I have successfully created an app which one of its functionality is open image file as then animate it once it was loaded.

It was:

• built with Apache Flex 4.15 with AIR 20
• packaged using native target so it could run under AIR runtime v20 installed on my PC
• NO error(s) in the project
• ran properly without any problems.

Recently I :

• update the AIR Runtime to v23
• run the installed app
• ... and surprisingly I got a weird image rendering.

I am running on Windows 8.1 X64

Here is the PROBLEM :

Here is the code (partial for the button fx):

What I've done so far

First Attempt:

• update Flex 4.15 SDK with AIR 23
• rebuild the app using updated Flex with AIR 23
• repackage the app using native target (-target native)
  RESULT: problem still occur

Second Attempt:

• using same SDK as the first attempt
• repackage the app using bundle target (-target bundle)
  RESULT: problem still occur

So I believe this is AIR problem

Since I use the app almost in daily basis, I have to repackage the app  using "-target bundle", back with Flex SDK AIR 20.
It works just like before.

However , I'd like to use the latest AIR runtime to get the latest security fixes, too.

Please help and thank you.
