AnimateWindow broken post-XP?

[dilettante]

I'm not sure when AnimateWindow quit working. I was sure it was working Ok even for a simple PictureBox in the past. But I can't get it working right for a UserControl either.

Something like a simple TextBox seems Ok yet, but I'm sure the issues necessary were addressed within common system controls like the one inside a TextBox.

This is broken on Windows 10 though it might work yet on something earlier:




I have two fixes but one has an awful flicker on Form Load (it has to make the UserControl visible to do a capture on it), here is the second one that works as desired:



Surely there is a better alternative though? The gyrations I'm going through seem beyond unnecessary.
