SnapsToDevicePixels seems to not work in StackPanel

Question

I have more expanders in StackPanel (Orientation=Vertical). When I expand one, the others below the expanded one seem to be blured. Like it would SnapsToDevicePixels=False.

I think the problem could be in StackPanel because it doesn't support UseLayoutRounding in .NET 3.5 (which I use) yet. Is that possible or the problem could be elsewhere?

I put SnapsToDevicePixels="True" almost everywhere I could, but nothing changed.

What type of Panel do you have inside the Expander? I tried with Grid and it was blurry. If I use another StackPanel inside the expander it looks fine. — SvenG, Nov 25 '11 at 10:52
@SvenG It's Grid. I tried StackPanel without success. It doesn't appear everytime. Different expanders make others blurry or not. It probably depends on how exactly it's placed on the pixels grid. — karel, Nov 25 '11 at 11:06

Try set UseLayoutRounding property it should adjust layout to use position rounded to integer. http://www.switchonthecode.com/tutorials/wpfs-most-important-property-uselayoutrounding

He said he used NET 3.5, why do you recommend something which is not available? – Zoli Aug 08 '16 at 09:51

I solved a similar problem with RenderOptions.EdgeMode="Aliased"
