Draw calls improvment and some UI strange bugs

UI UGUI

Hi,
I have ported my 3D game built only with GUI ( IN CUBE ACTION ) to the new 5.2 version and you can see the results here

Big improvements in draw calls!

Bugs:
Some UI elements were just missing ( text, images ),
some sliders showed strange behavior ( did not showed the sliding line all the way, if the slider was from 0-1, then if the value was <.3 slider line just vanished ),
some buttons were flicking wrong when mouse was getting in or out of them.

Every problematic UI element was world canvas, it had some position in 3D.
Every single problem was solved with the same fix.
I had to change ONE of the rect transform rotation, from 0 to any other value.
0.000001 was also solving the problem.

Do you a copy of the project folder from 5.1 so we can take a look at it importing fresh into 5.2?

Just to be on the same side.
You would like me to open the project in 5.1 and then to copy that project and open it in 5.2.
Not like I did from 5.0 to 5.2. OK i ll try that.

He is asking for you to give us you pre 5.2 copy. If you used 5.0 then give us the 5.0 project so we can open it in 5.2 ourselves and go through the upgrade path.
