How to reproduce: test the attached project with the latest version on a Windows 7 machine, notice that the font sizes are scaled, test the project with assemblies before  R2 2017 the fonts are not scaled

The issue is observed even with the RadControl.EnableDpiScaling property set to false. It would be expected that if the property was set to false, that the fonts would not be increased.

Workaround: change the fonts for each of the controls individually, the scaling can be calculated this way:
  Protected Overrides Sub OnShown(e As EventArgs)
        MyBase.OnShown(e)

        Dim dpi = NativeMethods.GetSystemDpi()
        Dim scale = dpi.X / 96.0
    End Sub

How to reproduce: create the following custom cell and notice that the collapsed elements would still occupy space inside the cell. Check the attached screenshot

public class PNUDFCellElement : GridDataCellElement
{
    public PNUDFCellElement(GridViewColumn column, GridRowElement row) : base(column, row)
    {
    }

    private CustomStackLayoutElement stack;
    private RadDropDownListElement radDropDownListElement;
    private RadDateTimeEditorElement radDateTimeEditorElement;
    private RadTextBoxControlElement radTextBoxElement;

    protected override void CreateChildElements()
    {
        base.CreateChildElements();
        stack = new CustomStackLayoutElement();
        stack.StretchHorizontally = true;
        stack.Orientation = Orientation.Horizontal;
        radDropDownListElement = new RadDropDownListElement();
        radDropDownListElement.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;
        radDropDownListElement.StretchHorizontally = true;
        radDateTimeEditorElement = new RadDateTimeEditorElement();
        radDateTimeEditorElement.StretchHorizontally = true;
        radTextBoxElement = new RadTextBoxControlElement();
        radTextBoxElement.StretchHorizontally = true;
        stack.Children.Add(radDropDownListElement);
        stack.Children.Add(radDateTimeEditorElement);
        stack.Children.Add(radTextBoxElement);
        this.Children.Add(stack);
    }

    protected override void SetContentCore(object value)
    {
        this.radDropDownListElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
        this.radTextBoxElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
        this.radDateTimeEditorElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

        this.DrawText = false;
        if (this.RowIndex % 3 == 0)
        {
            this.radDropDownListElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radDropDownListElement.Text = this.Value + "";
        }
        else if (this.RowIndex % 3 == 1)
        {
            this.radTextBoxElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
            this.radTextBoxElement.Text = this.Value + "";
        }
        else
        {
            this.radDateTimeEditorElement.Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }

        base.SetContentCore(value);
    }
}

public class CustomDataColumn : GridViewDataColumn
{
    public CustomDataColumn(string fieldName) : base(fieldName)
    {
    }

    public override Type GetCellType(GridViewRowInfo row)
    {
        if (row is GridViewDataRowInfo)
        {
            return typeof(PNUDFCellElement);
        }
        return base.GetCellType(row);
    }
}

Workaround: use a custom StackLayoutElemetn
public class CustomStackLayoutElement : StackLayoutElement

                stretchableCount++;
            }
            else
            {
                stretchableWidth += element.DesiredSize.Width;
                nonStretchableItems++;
            }
        }

        if (nonStretchableItems > 0)
        {
            stretchableWidth += ElementSpacing * (nonStretchableItems - 1);
        }

        int spacing = this.ElementSpacing;

        if (stretchableCount > 0)
        {
            stretchableWidth = (clientRect.Width - stretchableWidth) / stretchableCount;
            stretchableWidth -= spacing * stretchableCount;
        }

        ArrangeItemsHorizontaly(clientRect, finalSize, stretchableWidth, spacing);
    }

    protected override void ArrangeItemsHorizontaly(RectangleF clientRect, SizeF finalSize, float stretchableWidth, float spacing)
    {
        float x = clientRect.X;
        float y = clientRect.Y;

        List<RadElement> children = new List<RadElement>(this.Children);

        if (this.Comparer != null)
        {
            children.Sort(this.Comparer);
        }

        for (int i = 0; i < children.Count; i++)
        {
            RadElement element = null;

            if (this.RightToLeft && this.RightToLeftMode == RightToLeftModes.ReverseItems)
            {
                element = children[children.Count - i - 1];
            }
            else
            {
                element = children[i];
            }

            if (element.Visibility == ElementVisibility.Collapsed)
            {
                continue;
            }

            RectangleF proposedRect = new RectangleF(x, y, stretchableWidth, clientRect.Height);
            RectangleF finalRect = AlignRect(element, proposedRect);

            if (this.RightToLeft && this.RightToLeftMode == RightToLeftModes.ReverseOffset)
            {
                finalRect.X = finalSize.Width - x - finalRect.Width;
            }

            this.ArrangeElement(element, clientRect, finalRect, finalSize);

            x += finalRect.Width + spacing;
        }
    }

To reproduce:
public RadForm1()
{
    InitializeComponent();
    var a = new Author(null, "John");
    for (int i = 0; i < 20; i++)
    {
        radChat1.AddMessage(new ChatTextMessage("Item" + i, a, DateTime.Now.AddDays(-(20 - i))));
    }
    new Telerik.WinControls.RadControlSpy.RadControlSpyForm().Show();

    this.radChat1.ChatElement.MessagesViewElement.TimeSeparatorInterval = TimeSpan.FromDays(1);
}

You will notice that there is today in several places. 

Workaround:
this.radChat1.ChatElement.MessagesViewElement.TimeSeparatorInterval = TimeSpan.Zero;

var a = new Author(null, "Forest Gump");
for (int i = 0; i < 20; i++)
{
    radChat1.AddMessage(new ChatTextMessage("Item" + i, a, DateTime.Now.AddDays(-(20 - i))));

    ChatTimeSeparatorDataItem separator = new ChatTimeSeparatorDataItem(new ChatTimeSeparatorMessage(DateTime.Now.AddDays(-(20 - i))));
    radChat1.ChatElement.MessagesViewElement.Items.Add(separator);
}

Note: other operations that affect the image's size should also handle large images.

No Workaround.

It is possible to create a custom resize dialog as follows:
        public class MyRadImageEditor : RadImageEditor
        {
            protected override RadImageEditorElement CreateImageEditorElement()
            {
                return new MyRadImageEditorElement();
            }
        }

        public class MyRadImageEditorElement : RadImageEditorElement
        {
            public override void ShowResizeDialog()
            {
                this.ShowDialog(typeof(MyResizeDialog));
            }
        }

        public class MyResizeDialog : RadForm
        {
            public MyResizeDialog(RadImageEditorElement imageEditorElement)  
            {
               
            }

            //TODO custom dialog

1.Drag a RadGridView to a form
    2.Click Dock in parent from its SmartTag menu
    3.Now change the Dock to None from the Properties window
    4.Open again the smart tag and you will see that the link's text is "Undock in parent container" but the control is not docked.

The same issue occurs with all controls that have "Dock in parent container" action link.

The button indicating the RadDropDown draws just a think border on the left-side instead of drawing a thin four-sided border around the arrow.
