Extreme slow-down in Windows FMX app UI since upgrading to 12.1

[Cristian Peța 122]

Using arrRect.SetBounds() you avoid a call to AlignObjects because TControl.SetBounds is checking some things before a call to AlignObjects

Avoid setting TPosition.X

Thanks @Cristian Peța

I've updated my sample project on https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-3711

Hope they found a way to optimize this for 13.

Just wanted to try a fix in FMX.Forms and I found it already there but commented 🤔.

First two lines will exit and AlignObjects() will not be called if used Form.BeginUpdate. The Realign will be done anyway after Form.EndUpdate.

procedure TCustomForm.Realign;
begin
//  if FDisableAlign or (FUpdating > 0) then
//    Exit;
... more code
  if FCanvas <> nil then
  begin
    AlignObjects(Self, Padding, FCanvas.Width, FCanvas.Height, FLastWidth, FLastHeight, FDisableAlign);
    RecalcControlsUpdateRect;
    InvalidateRect(ClientRect);
  end;
end;

Now, that's odd. As if someone forgot to uncomment before release...

I updated the report https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-3711

Maybe it is commented out to fix some strange issue/bug.  In that case the developer that has commented out the code should include the report number in the comment to document the change in behavior.

It's probably done on the commit comment with an internal ticket number. No reason to put it in the source file on the comment visible by the public (= us).

Most probably yes. It would be easier if we could get that information. I do hate when on codebase I am working on changes like this does not have a comment with a proper description or ticket number. Searching in repository for the specific change can be time consuming.
