Tracy, Assuming you are anchoring both the pageframes and the contained editbox (I have used Anchor=10) than on Windows 10 64Bit I don't get any problems at all.

Hello,

A Form - MyForm A PageFrame - MyForm.pgf A 2nd PageFrame - MyForm.pgf.Page2.InnerPgf An Editbox - MyForm.pgf.Page2.InnerPgf.Page2.edt

Set the MyForm.pgf.Page2 active Set the MyForm.pgf.Page2.InnerPgf.Page2 active

Now stretch the form down quickly.

In Windows 10, on 3 different machines, we are seeing the scrollbar of the editbox ghost over MyForm.pgf.Page2

Anyone want to try to duplicate that and share your findings?

Thank you, Tracy

With your anchor settings still no problems seen.

However my video card Is a high spec Nvidea with 11Gb on board it.

I'll certainly try it on a lower spec machine and report back

Hi Dave,

I did forget about mentioning the anchors.

MyForm.pgf.Anchor = 15 MyForm.pgf.Page2.InnerPgf.Anchor = 14 It is set on the lower half of the page. MyForm.pgf.Page2.InnerPgf.edt.Anchor = 0

All the classes used are subclasses from the VFP.

I found the artifact will appear when stretching the window down quickly.

However, I just built a test form and I am seeing the artifact appear using base classes.

Thank you for tinkering, Tracy

Mike,

Yes, it does prevent the artifact from appearing. Reading what REFRESH does, makes me cringe a little to use it in this way. Every control will refresh its data, not just a redraw of the screen area.

Just a WAG -- In the thisform.Resize event, does adding a this.refresh fix it?

Well you don't change any data in Refresh events, right? ;-)

Perhaps try the thisform.Lockscreen instead of .Refresh?

Late on a Friday here at the office, I put this in a prg and still see the behavior.

oTest = CREATEOBJECT("pageframeartifact") oTest.Show()

oTest = .NULL. CLEAR CLASS pageframeartifact

DEFINE CLASS pageframeartifact as Form

windowtype = 1 caption = "Active Page 2 of both pageframes - Pull down quickly"

ADD OBJECT pgf as pageframe WITH ; pagecount = 2, anchor = 5, width = 450

PROCEDURE init this.height = 250 this.Width = 450 this.pgf.page2.addobject("pgf", "pageframe") this.pgf.page2.pgf.height = 100 this.pgf.page2.pgf.top = 116 this.pgf.page2.pgf.width = 450 this.pgf.page2.pgf.pagecount = 2 this.pgf.page2.pgf.anchor = 14 this.pgf.page2.pgf.visible = .T. this.pgf.page2.pgf.page2.addobject("edt", "editbox") this.pgf.page2.pgf.page2.edt.top = 10 this.pgf.page2.pgf.page2.edt.left = 10 this.pgf.page2.pgf.page2.edt.width = this.Width - 20 this.pgf.page2.pgf.page2.edt.height = 60 this.pgf.page2.pgf.page2.edt.visible = .T. ENDPROC

ENDDEFINE

Odd, I can make it happen on 3 different machines. 2 Desktops and another a laptop. All have different Video cards.

You can see a scrollbar just floating on pgf.page2. I increased the height of the form by pulling straight down, not from the corner.

Your example performs faultlessly as did mine done using the designer.

Looks like a video card rendering problem to me.

Tracy, I agree with Ted... 32Gb Intel i7 Windows 10 64 bit NVidea GTX 1080 (12Gb Memory) and no ghosting at all.

I have done a video of it if you want to see.

Runs fine, no ghosting.

Can you repro in Safe Mode, VGA? I'm inclined to blame video cards.
