Graphics 2.0 - Jittering Text

Solar2D Advanced Graphics
#1

There is a bug involving text in a display group in Graphics 2.0.

When a display group is rotated, any text that is in it jumps around 1-2 pixels.

Smaller text is more noticeable.  This does not occur in Graphics 1.0, and occurs on device only.

I mainly tested this on the iPad 2 and 3, but it also happens on the iPhone.

It is also most noticeable when the text is nearer to a 45 degree angle.

I submitted a bug report, bug have not received a number yet, I’ll post it here as soon as I do.

I just wanted to see if anyone else has noticed this issue.

Reproduce as follows:

Create a few text objects.

Insert them into a display group.

Slowly rotate the display group.

You will see each text object jumping around independently.

I uploaded the test file that I submitted with the bug report as well.  You can build this to device using either 1.0 or 2.0, (note graphicsCompatibility is not on).  The text jittering only occurs when built with the 2.0 engine.

EDIT:

The case number is 29027 - Tom already confirmed it and sent it to Engineering to be fixed.

I am having the same problem. I have child textboxes within a display group that is being rotated and moved about. The text sorta “skips a beat” and bounces before being settled where it should. It is ongoing however and is more than a few pixels. More like 10 pixel jumps. Big problem really, I now have to disable a feature.
