FireMonkey：Android上缺少抗锯齿和抖动效果

我在Delphi10.4（FMX）中用TArc创建了一个进度动画，但在Android上运行该应用程序时会出现一些奇怪的渲染行为

像TArc或TLine这样的简单形状似乎都没有抗锯齿功能。将

t格式.Quality

设置为

HighQuality

似乎没有效果

设置

Arc1.Stroke.Cap:=TStrokeCap.Round

似乎对Android没有影响。两端一点也不圆*

TFloatAnimation似乎存在某种抖动问题，但我无法找到原因*

*在Windows（10）上运行应用程序时，一切看起来都很好，但在Android上存在这些小故障，我想知道问题出在哪里。尤其是缺少抗锯齿。智能手机上的显示器是高密度的，但丢失的抗锯齿仍然清晰可见。以下是从Android设备和运行Windows 10的台式PC上捕获的视频：

下面是一个示例代码：

Unit1.fmx

object Form1: TForm1
  Left = 0
  Top = 0
  Caption = 'Form1'
  ClientHeight = 344
  ClientWidth = 427
  Fill.Color = claLightskyblue
  Fill.Kind = Solid
  FormFactor.Width = 320
  FormFactor.Height = 480
  FormFactor.Devices = [Desktop]
  DesignerMasterStyle = 0
  object Arc1: TArc
    Align = Center
    Size.Width = 60.000000000000000000
    Size.Height = 60.000000000000000000
    Size.PlatformDefault = False
    Stroke.Color = claWhite
    Stroke.Thickness = 5.000000000000000000
    Stroke.Cap = Round
    EndAngle = 90.000000000000000000
    object FloatAnimationStartAngle: TFloatAnimation
      Enabled = True
      Duration = 2.000000000000000000
      Loop = True
      PropertyName = 'StartAngle'
      StartValue = 0.000000000000000000
      StopValue = 360.000000000000000000
    end
    object FloatAnimationEndAngle: TFloatAnimation
      Enabled = True
      Duration = 2.000000000000000000
      OnFinish = FloatAnimationEndAngleFinish
      PropertyName = 'EndAngle'
      StartValue = 1.000000000000000000
      StopValue = 360.000000000000000000
    end
  end
end

Unit1.pas

// ...stripped code here at top...
implementation

var
  increasing: Boolean = True;

{$R *.fmx}

procedure TForm1.FloatAnimationEndAngleFinish(Sender: TObject);
begin
  FloatAnimationEndAngle.Enabled := false;
  FloatAnimationEndAngle.Inverse := not FloatAnimationEndAngle.Inverse;

  if increasing then
    FloatAnimationEndAngle.Duration := FloatAnimationEndAngle.Duration * 2.0
  else
    FloatAnimationEndAngle.Duration := FloatAnimationEndAngle.Duration / 2.0;

  increasing := not increasing;
  FloatAnimationEndAngle.Enabled := true;
  FloatAnimationEndAngle.Start();
end;
