Re: [flexcoders] Re: Rendering Problem
That's interesting that Steve mentioned autoLayout. We had a similar problem with a bunch of image rollovers that were all flickering as a group, and it turned out to be that because we hadn't told them their height or width, they were having to lay themselves out to find out - hence the flicker while it figured all that out. But your problem is so broad that I encourage you not to apply possible cures until you understand it better. A basic plan is to cut stuff out until you don't see the problem any more.

What could be causing problems with rendering?! I have this application that every now and than flicks, the background goes white for a second than get back to normal. Its not really something in particular because that happens in a couple of components i create. One in particular that do pretty much the same as the date, opening a popup on the side, but everytime i open that i get this flickering problem. Any clue what could be causing that? i know its a very empty qustion but maybe someone might give me an idea what often causes flex to flick. thanks raf
RE: [flexcoders] Re: rendering problem
Hard to say w/o more information. I would try to see if the number of children matches what you see on screen. Maybe write some code that shows you what is on the display list and then try to find out how duplicates are getting created if there are any. For the DG problem, make sure the renderers aren't doing things with masks.
