Popup/new windows seems to tear, quickly disappear/reappear, and go off frame occasionally for fraction of second when clcking on moving it.

I must have gone about creating the window the wrong way? It keeps blinking/flashing a lot. I have tested in multiple terminals (ExtraTerm, Gnome Terminal, Tilix, and Yakuake)

Here is an example of the flashing:

Here is one I just took, the quality is lacking in exchange for much higher framerate. You can definitely see the crazyness.

I don't believe I am doing anything incorrectly in code for the screen tearing/jitter, etc?

(P.S. Aside from these silly issues. I absolutely love the way things are starting to come out. It definitely takes some time and effort, but it really am starting to like the outcome)

func CreateTableDialog(btn *ui.Button, tableTitle string) {
	tableDialog := new(TableDialog)

	// --- Obtain terminal overall size ----------------------------------
	cw, ch := term.Size()

	// --- Save current values to temp value until saved -----------------
	tmpAssetData = AssetDetail

	// --- Create new popup window for table data ------------------------
	tableDialog.View = ui.AddWindow(cw/2-75, ch/2-16, ui.AutoSize, ui.AutoSize, TxtAssetCodes)
	ui.WindowManager().BeginUpdate()
	defer ui.WindowManager().EndUpdate()
	tableDialog.View.SetGaps(1, ui.KeepValue)
	tableDialog.View.SetModal(true)
	tableDialog.View.SetPack(ui.Vertical)

	tableDialog.Frame = NewFramedWindowInput(tableDialog.View, tableTitle, nil)

	// --- Create data table ---------------------------------------------
	td := ui.CreateTableView(tableDialog.Frame, 145, 15, 1)
	ui.ActivateControl(tableDialog.Frame, td)

NewFramedWindow is just a smaller helper with some defaults that I can over ride by passing something in. Mostly for practice and helping make things a bit cleaner.

func NewFramedWindowInput(parent *ui.Window, title string, params *FramedInputParams) *ui.Frame {

	if params != nil {
		SetValues(params)
	}

	frameWindowReturn := ui.CreateFrame(parent, defaultWidth, defaultHeight, defaultBorder, defaultScale)
	frameWindowReturn.SetPaddings(defaultPadX, defaultPadY)
	frameWindowReturn.SetPack(defaultOrientation)
	frameWindowReturn.SetTitle(title)
	return frameWindowReturn
}

Interesting effect. I did not move windows much with a mouse and did not notice it before. But after trying to move a windows in maindemo with mouse around fast, I experienced the same issue. I am not sure how to fix it - I'll look into it later

No problem. It is appreciated. It usually happens the most if you move one, but there are times when it also happens when scrolling up/down/left/right in a table or text field. It seems to only happen when there is one window overlapping another, and it is the top window that does it in my experience so far.
