Question by shadiradio · Dec 10, 2015 at 02:27 AM · animation2dspritebug5.3

2D Sprite animations flicker on first run in Unity 5.3

Since updating to 5.3, all my sprite animations will flicker whenever they are first run. After the first time, they play fine. This happens in the editor as well as builds. However if I quit the editor and launch it again, everything will reset and they'll flicker on first-view again. Any ideas?

I have the same problem, on the first display of a sprite it flickers. I think it may have to do with this change:

"Lastly, we’ve enabled asynchronous loading of texture data from disk and time-sliced uploading to the GPU on the render thread. This reduces waiting times for texture GPU uploads in the main thread, which should result in overall improved rendering performance."

Good catch, that definitely seems like a plausible culprit for this. All of my sprites that are part of the animations are part of an atlas texture though, so that's strange as well. I hope there's a way to disable this, or it will be fixed in the next patch.

Think this is the same issue http://forum.unity3d.com/threads/5-3-elements-in-the-ui-flicker-between-different-sprites.373098/#post-2419646

I've filed a bug report.

Hey, what is the report nr?

issue 753349. Doesn't appear to be on Issue Tracker. Unity QA couldn't build my 5.3 project with 5.2 because i'd integrated Unity Purchasing so they couldn't get a comparison between versions. Not sure what happens to the ticket now.

Reading the report. Okay, any way to strip it down to bare $$anonymous$$imum, without the IAP integration? Reports only show up in IT once they have been verified by QA, need a project that can be built in this case.

No, unfortunately not. I submitted a 5.2 compatible version of my project to the same bug report, but i've not heard anything since.

Exactly the same problem here, sprites are flickering (on Android build) after upgrading to 5.3. The problem occurs on Galaxy S3 during UI element's animation (the sprite which flickers is not animated, the other ones are - simple position translation). When different scene during the runtime is loaded and then afterwards I get back to the original scene where the problem occurred the element stops flickering and behaves normally.

Here to, but all my sprites, buttons my whole UI are flickering and not just in the first-view. And on my android build, the gameObjects meshes are flickering too.
