I would be glad if you could re-run the compatibility tests (the four of them; they look similar but each of them test different settings) and thus confirm the generated code works well in your configuration.
Ouch. That's right. The 16x16 and 32x32 PNG icons are inverted in the current version. Clearly a bug. It was introduced during the refactoring that took place in 2014Q4 when writing the non-interactive API. Thank you for reporting!
The fix itself it simple and I updated the compatibility tests to reflect the change, so this new version can be tested right now.
However I will have a very limited bandwidth this week so I won't be able to re-run the tests and deploy the fix.
