Release R3 2019 (LIB 2019.2.729)
I have RadDiagram on Form and registered ShapeDoubleClicked event on it.

After double click on a shape I open another modal form (let's call it form2). The second mouse click is fired on a modal form (Form2) which in some cases, based on shape position in Form1 (precisely when the shape is in center of the screen), change the state of my ToogleSwitch which is in center of Form2.

        Dim radioPrimitive As RadioPrimitive = Me.RadRadioButton1.ButtonElement.CheckMarkPrimitive.FindDescendant(Of RadioPrimitive)()
        radioPrimitive.MinSize = New Size(21, 21)

- The first click should be disabled and the event should fire after the interval in the delay property. 

Workaround:
Me.RadRepeatButton1.Delay = 7000

    InitializeComponent();

    this.radSplitButton1.DropDownButtonElement.DropDownMenu.MaximumSize = new Size(30, 0);
    RadScrollBarElement element = this.radSplitButton1.DropDownButtonElement.DropDownMenu.PopupElement.FindDescendant<RadScrollBarElement>();

To reproduce: apply the Window8 theme to the entire application containing a RadButton and a RadCheckBox. Change the color of RadButton to Green and handle the RadCheckBox.ToggleStateChanged event in order to enable/disable the button. You will notice that after disabling once the button enabling it again, the ButtonFillElement.NumberOfColors property is set to 1 and gradient color becomes solid. Please refer to the attached sample project and gif file.

Workaround:

int numberOfColors = 0;

private void radCheckBox1_ToggleStateChanged(object sender, Telerik.WinControls.UI.StateChangedEventArgs args)
{
    if (args.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On)
    {
        this.radButton1.Enabled = true;
        this.radButton1.ButtonElement.ButtonFillElement.NumberOfColors = numberOfColors;
    }
    else
    {
        numberOfColors = this.radButton1.ButtonElement.ButtonFillElement.NumberOfColors;
        this.radButton1.Enabled = false;
    }
}

Please refer to the attached sample project and gif file. The text gets clipped sometimes when resizing the form. It may become even blurry. This problem is observed with the MS Form, but it is not reproducible with RadForm.

Workaround: use a RadForm

UPDATED: a second project is attached (00393359CheckBoxDisabledUPDATED.zip). The MissingCheckBoxesText.gif illustrates the incorrect behavior. In this case, the UseCompatibleTextRendering property is set to false.
Workaround for the second case: instead of setting the RadCheckBox.Enabled property to false, disabled the check primitive and make the text gray as follows:

private void radButton1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 30; i++)
    {
        RadCheckBox cb = new RadCheckBox();
        cb.Text = "RadCheckBox " + i;
        cb.Location = new Point(10, i * 30); 
        cb.ButtonElement.CheckMarkPrimitive .Enabled = false;
        cb.ButtonElement.TextElement.ForeColor = Color.Gray; 
        cb.ButtonElement.ShouldHandleMouseInput = false;
        cb.UseCompatibleTextRendering = false;
         
        this.Controls.Add(cb);
    }
}

The same case is valid for RadToggleButton as well.

To reproduce: use the following custom RadCheckBox. You will notice that the ToggleStateChanging, ToggleStateChanged, PropertyChanged, CheckStateChanging, CheckStateChanged won't fire anymore:

public class MyCheckBoxElement : RadCheckBoxElement
{
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadCheckBoxElement);
        }
    }
}

public class MyCheckBox : RadCheckBox
{
    protected override RadButtonElement CreateButtonElement()
    {
        return new MyCheckBoxElement();
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadCheckBox).FullName;
        }
    }
}

Workaround:

public class MyCheckBoxElement : RadCheckBoxElement
{
    protected override void OnKeyDown(KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            return;
        }

        base.OnKeyDown(e);
    }

    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadCheckBoxElement);
        }
    }
}

public class MyCheckBox : RadCheckBox
{
    protected override RadButtonElement CreateButtonElement()
    {
        MyCheckBoxElement checkBox = new MyCheckBoxElement();
        checkBox.ToggleStateChanging += new StateChangingEventHandler(ButtonElement_ToggleStateChanging);
        checkBox.ToggleStateChanged += new StateChangedEventHandler(ButtonElement_ToggleStateChanged);
        checkBox.PropertyChanged += new PropertyChangedEventHandler(res_PropertyChanged);
        checkBox.CheckStateChanging += new CheckStateChangingEventHandler(res_CheckStateChanging);
        checkBox.CheckStateChanged += new EventHandler(res_CheckStateChanged);
        return checkBox;
    }

    private void res_CheckStateChanged(object sender, EventArgs e)
    {
        base.OnCheckStateChanged(e);
    }

    private void res_CheckStateChanging(object sender, CheckStateChangingEventArgs args)
    {
        base.OnCheckStateChanging(args);
    }

    private void res_PropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        if (e.PropertyName == "IsChecked")
        {
            base.OnNotifyPropertyChanged("IsChecked");
        }
    }

    private void ButtonElement_ToggleStateChanged(object sender, StateChangedEventArgs args)
    {
        base.OnToggleStateChanged(args);
        base.OnNotifyPropertyChanged("Checked");
        base.OnNotifyPropertyChanged("CheckState");
        base.OnNotifyPropertyChanged("ToggleState");
    }

    private void ButtonElement_ToggleStateChanging(object sender, StateChangingEventArgs args)
    {
        base.OnToggleStateChanging(args);
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadCheckBox).FullName;
        }
    }

When you customize a theme for RadSplitButton, you are not able to change the color of the action button element when it is pressed and the drop down is not opened. 

Workaround:
this.radSplitButtonElement2.ActionButton.MouseDown+=ActionButton_MouseDown;
this.radSplitButtonElement2.ActionButton.MouseUp+=ActionButton_MouseUp;

private void ActionButton_MouseUp(object sender, MouseEventArgs e)
{
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
}

private void ActionButton_MouseDown(object sender, MouseEventArgs e)
{
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.BackColor = Color.Red;
    this.radSplitButtonElement2.ActionButton.ButtonFillElement.GradientStyle = GradientStyles.Solid;
