I have similar experiences as well. In fact, badly designed itemrenderers
cause lags even in non-Flex iOS and Android apps. I have seen this in
numerous apps.
Is there something we can do about this in terms of coding/compiler
warnings etc. ? Or perhaps have a Flex PMD rule for this?
At the very least, we should have documentation on our docbase that talks
about this issue. Is that something you could help with?
Thanks,
