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, Om
