iOS Metal Api form doesn't fit on screen

[enesgeven 6]

Hi,

 

I found this bug today, I reported already embc but I need also tips about this bug.

 

When Delphi FMX iOS Metal Api enabled and iPhone Settings>Display&Brigtness>View>Zoomed options is enabled delphi form doesn't fit on screen.

When Metal Api or iPhone Zoomed setting is disable, everything is normal, like that:

When Metal Api and iPhone Zoomed setting is enable, form doesn't fit on screen, like that:

(Tested with Delphi 10.4.1 clean and empty project)

Can I try anything about fix this issue? before embc officially fix, I need quick solutions.
Thank you.

Where did you turn Metal on? To true?
It should be done in the .dpr file, not in a .pas file... That makes a lot of difference.

Something like

 

....

{$R *.res}

begin
      {$IF DEFINED(iOS) or DEFINED(MACOS)}
         GlobalUseMetal := True ;
      {$ENDIF}

  Application.Initialize;

Thank you.

Yes I am doing like that on .dpr before Application.Initialize;

also I tried on main form .pas initialization but both same result.

 

I did this for temporary, when device Display Zoom setting is Zoomed not activating metal api, this will reduce performance but at least application will work.

    if TUIScreen.Wrap(TUIScreen.OCClass.mainScreen).nativeScale=TUIScreen.Wrap(TUIScreen.OCClass.mainScreen).Scale then
    begin
      GlobalUseMetal:=true;
      GlobalEventDrivenDisplayUpdates:=False;
      GlobalPreferredFramesPerSecond:=60;
    end;

Hi @enesgeven! 

 

I didn't find this issue in the quality portal so I reported it: https://quality.embarcadero.com/browse/RSP-37935

Just a tip: This issue is fixed in the latest version of Skia4Delphi (3.3.2). Not only this problem but a dozen others. Our Metal is as stable as OpenGL. Just enable Skia4Delphi as your app's renderer, and all issues will be resolved.
