I was wondering if anyone knew the nature of why some png icons make a "bubble" around them when used in a theme and some don't. Is it a setting in the applications info.plist ? Some other setting I can change? In one case the exact same icon was without bubble when applied to AppStore and created a bubble when it was applied to Mocha VNC Lite. I suspected that maybe this was because one resides in /private/var/stash/Applications and one in /private/var/mobile/Applications , but then I noticed that it couldn't be because I have an app in mobile which bubbles also. Anyone know what the deal is?
