moisestafolla... Thanks to your concern it was a problem with the bit.. I was using 64 bit Unity 5 and so it wasn't working. I downloaded the 32 bit version and it started working. Thanks to vuforia. :)

Which Unity version are you using? Is this happening in the sample apps? Have you tried with the latest Vuforia release?

Vuforia 4.0.105 with support for Unity 5.0 has been released; this release should also fix the scanline issue (and you should no longer need to use the ScanlineFix script).

Ok, thanks for confirming.

Meanwhile,

we  expect to release an updated release of 4.0 very soon, which should also include a native fix for the scanline issue,  so that you will no longer need to use the "ScanlineFix" script as a workaround in Unity;

That should solve your issue without requiring any additional workarounds.

This is expected very soon (stay tuned and bear with us in the next days...)

Hi,

have you attached the ScanlineFix script from here:

https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/vuforia-40-and-unity-50

?

This is supposed to be attached to the Camera object under the ARCamera in Vuforia 4.0; if you attached it to the ARCamera itself, you should remove it from ARCamera and attach it to the child Camera object;

have you tried that already ?
