Atlas Maker Popup is a CPU eater?

[r.pedra]

Hi,
I noticed something with the Atlas Maker. I snapped it into the Unity main window and it is often displayed.
Everytime the Atlas Maker is displayed Unity needs 70% of CPU and when i switch on another tab of my layout in Unity, it gets back to a normal value.
I attached some screenshots to illustrates what I'm saying. (Same thing seems to happen with the Font maker)

Is this normal? Or is this something that you can optimize?

That's weird I just noticed the same thing this morning in my project. The way I saw what was happening was by opening Unity's Profiler and checking "Profile Editor". The UIAtlas window was causing a lot of CPU work as it was constantly listening for changes and image file selection. So I closed the UIAtlas window and everything went back to normal.

I have always had the UIAtlas up in my layout and it never caused any problem before. But I had noticed something was wrong since the last NGUI update (or maybe the one before); Unity was slower than usual and "acting busy". It's just a coincidence that I managed to find out where that was coming from and I saw your message one hour later...

Interesting... I will look into this when I return from GDC.

Sounds like something is going heavy work in a OnGUI script in UIAtlasMaker or something like that.

UP (In case the GDC erased your internal brain memory  )

It did! Thanks for the reminder.

You can fix it by modifying UIAtlasMaker.OnSelectAtlas function to this:

1.         void OnSelectAtlas (Object obj)
2.         {
3.                 if (NGUISettings.atlas != obj)
4.                 {
5.                         NGUISettings.atlas = obj as UIAtlas;
6.                         Repaint();
7.                 }
8.         }

Hi, it worked yesterday but today it's still eating my cpu.
DockAera.OnGUI have a 10ms cycle and 75.5Kb of allocation.(Still happening only when Atlas Maker is open).
It's falling to 1.4ms when I have the Atlas setted to None and nothing selected.(But my CPU is still at 80% )

Likely the Font Maker this time, not the atlas maker. It has the same exact function with the same problem.
