Did you have PPAA enabled in the View?

view.SetFlags(RenderFlags.PPAA);

• Default means it will use whatever you have set in the View (this is the default value for the property).
• Disabled means PPAA is not used on that element subtree (remark that this property is inheritable).

Thank you, Sergio!

You're totally right, I didn't set RenderFlags.PPAA! Somehow I've totally missed this NoesisGUI changelog entry "Removed SetIsPPAAEnabled and GetIsPPAAEnabled from IView. PPAA is now part of RenderFlags enumeration".
I was under impression that the new PPAAMode properly of FrameworkElement is enough.
Oddly enough, it seems the change was done long ago (3.0.0b1) but I've noticed lack of PPAA only few days ago. I swear it worked fine until recently!

By the way, Is there any harm in keeping RenderFlags.PPAA for the View even if I set it to PPAAMode to Disabled for the View's content? Or it's best to set it only when we actually want to apply PPAA?

Regards!

If you want to disable PPAA you should do it by removing the RenderFlags.PPAA in the View, because even if you set PPAAMode to Disabled in View's content that won't inherit on Popups (they are not children of the content).

It is better to use PPAAMode just for disabling PPAA on parts of the UI where you don't need antialiasing (for example on square/rectangle shapes).

Thank you for the explanation, Sergio! It makes perfect sense.
It's worth to mention about this detail in this doc page https://www.noesisengine.com/docs/Gui.Core.AntialiasingTutorial.html

Please close this ticket and sorry for disturbing you!
