Flickering Issue

[PebbleBug]

Yes, fixes the flickering issues for me.
Thanks.

[kofight]

Fixed, thanks

Unfortunately in the process I broke something else <_<

...so I just re-uploaded f2 with a fix for that. Readme wasn't updated anyway.

This is still an issue for us (maybe we are doing it wrong  ). It looks like the whole UI flickers sometimes. Everytime I have encountered flickering, the following happens:

• Frame n: UIPanel.Find() is called, mRebuild is set to true, and full draw call rebuild is triggered on LateUpdate().
• Frame n + 1: All UI widgets are missing.
• Frame n + 2: All UI widgets are visible, but some are ill-positioned (centered).
• Frame n + 3: All UI widgets are shown properly.

This happens on both editor on PC and on iOS devices, so I guess it's not platform dependent. I have tested with the latest version 3.0.6 f3 on Unity 4.2.2.

3.0.6.f3 resolved the flickering issues I had

I know the asset store had 2 versions of NGUI on earlier, might be worth checking it wasn't a botched update?

[Antti]

Re-downloaded and re-imported NGUI, I have the latest version for sure.

[ArenMook]

I can use a repro case, Antti.

That's the flickering resolved for me, thanks Aren. The alpha stuff still happens, but my workaround works fine for that.

Got the latest update. Can confirm it fixes all my issues. Thanks so much for that fast fix!

I appear to be getting occasional flickering (nothing like before where the whole panel would break) when I turn on/off a widget using setactive(). Im not entirely sure if this happened previously or not, but I feel like I haven't seen it before. It only happens for what appears to be a single frame.

[Antti]

We got our issue solved.

We had a bug in our code: we occasionally created a widget under a wrong parent, having no panel in the ancestors of the UI hierarchy.

(Thanks for the latest performance optimizations btw! We appreciate them a lot

If you have any "before" and "after" profiler screenshots, I'd be very curious to see them

[Antti]

Here are profiler screenshots from the same scene, first with NGUI 3.0.4, then with 3.0.6 f3.

There where other changes than NGUI version between those builds too, e.g. the spikes you see in 3.0.4 are gone because of those.

But AFAIK the CPU time difference 2.32 -> 1.22 and the absence of memory allocations should be directly contributable to NGUI optimizations.

On 3.0.6f4.

I have flickering problem too...
But mine happen when the scene toggle.
Just a quick flick but annoying.

Between OnEnable Update and where they anchoring succeeds sprite render one frame. It is necessary to add a forced binding while OnEnable.

UIWidget.OnEnable()
+UpdateAnchors();
