[Lazarus] Visual "uglyness" when creating TSynEdit @ runtime in my app

I have a text editor (LazEdit on Lazarus CCR) which uses a
TPageControl to act like a Tabbed Document Interface (much like
Upon creating a new Tab it basically does:
- Add a new TTabSheet to the PageControl
- Create an instance of a TSynEdit
- Set TSynEdit.Parent to the newly created TTabSheet
- Set TSynEdit.Align := alClient
This works as expected.
However there is one visual anomaly: when you create a new Tab, for a
brief moment you can see the TSynEdit, unaligned, with Width and
Height set to it's defaults (like you would drop it on a Form in
Long time ago, in Delphi, I solved this by doing:
//Create the TSynEdit, align it etc.
This delayed any painting up to the point the TSynEdit was aligned.
However, this is a Windows only fix.
The relevant code is at:
(function TEditorPageControl.AddPage: TEditor; appr. at line 994)
Does anyone have a suggestion how to fix this in a cross-platform manner?
