editor changes size and position of canvas

Hi there,

I have a big problem. Because of some issues before I patched Unity to 4.6.1p4 today. The patch solved my problems but bring some new problems in it:

I have a Canvas with a Test-Canvas and a Background-Canvas. Test and Background are at the same position, same size same anchor. In booth canvas is the same image. To sum up - booth canvas are the same.

Issue 1
When I press the play button the Test-Canvas is now repositioned and resized, the Background-Canvas is on the same position.

Issue 2 (I repositioned the Test-Canvas to his original position)
When I save the scene and the project and reopen it the Test-Canvas is on another place and has another anchor.

 

I have tested now some unity patches. The problem doesn't appear at unity 4.6.1 and 4.6.1p1
Since 4.6.1.p2 it happens (i haven't tested 4.6.1p3)
