升级到 Delphi XE5 和最新的 GLScene 后，在某些 PC 上，TGLSceneForm 会使应用程序完全崩溃（请参阅下面的日志文件）。但是，如果我使用完全相同的应用程序并在 Delphi 2010（使用旧版本的 GLScene）中编译它，它就可以完美运行！

它仅在某些 PC 上执行此操作。例如，我们办公室有 3 个 HP 工作站，XE5 应用程序 2 个工作正常，1 个崩溃（具有不同的图形适配器）。然而，在 Delphi 2010 中编译时，所有 3 台 PC 的工作都正常！

应用程序中的 GLScene 日志文件是：

示例代码如下：

program GLSceneError;

uses
  EMemLeaks,
  EResLeaks,
  EDialogWinAPIMSClassic,
  EDialogWinAPIEurekaLogDetailed,
  EDialogWinAPIStepsToReproduce,
  EDebugExports,
  EFixSafeCallException,
  EMapWin32,
  EAppVCL,
  ExceptionLog7,
  Vcl.Forms,
  ufrmMain in 'ufrmMain.pas' {frmMain},
  ufrmGLScene in 'ufrmGLScene.pas' {frmGLScene: TGLSceneForm};

{$R *.res}

begin
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TfrmMain, frmMain);
  Application.Run;
end.

unit ufrmMain;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls;

type
  TfrmMain = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  frmMain: TfrmMain;

implementation

{$R *.dfm}

uses ufrmGLScene;

procedure TfrmMain.Button1Click(Sender: TObject);
begin
  try
    if not Assigned(frmGLScene) then
      Application.CreateForm(TfrmGLScene, frmGLScene);

    frmGLScene.Show;
  except
    on E: Exception do
    begin
      ShowMessage(E.Message);
    end;
  end;
end;

end.

object frmMain: TfrmMain
  Left = 0
  Top = 0
  Caption = 'frmMain'
  ClientHeight = 182
  ClientWidth = 199
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  PixelsPerInch = 96
  TextHeight = 13
  object Button1: TButton
    Left = 32
    Top = 32
    Width = 141
    Height = 57
    Caption = 'Open GLScene Viewer'
    TabOrder = 0
    OnClick = Button1Click
  end
end

unit ufrmGLScene;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  GLScene, GLSceneForm;

type
  TfrmGLScene = class(TGLSceneForm)
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  frmGLScene : TfrmGLScene;

implementation

{$R *.dfm}

end.

object frmGLScene: TfrmGLScene
  Left = 246
  Top = 74
  Caption = 'GLScene'
  ClientHeight = 326
  ClientWidth = 405
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  Position = poMainFormCenter
  Buffer.BackgroundColor = 2064383
  FullScreenVideoMode.Width = 1920
  FullScreenVideoMode.Height = 1080
  FullScreenVideoMode.ColorDepth = 32
  FullScreenVideoMode.Frequency = 50
  PixelsPerInch = 96
  TextHeight = 13
end

我不知道该转向哪里，因为这似乎是自升级到 XE5 以来 GLScene 的某种基本问题。我无法推出需要我们所有客户对图形适配器进行故障排除的软件，特别是因为它在完全相同的 PC 上运行 Delphi 2010，所以我知道不是我们的程序导致了问题。

任何想法或帮助将不胜感激。瑞克。

错误很明显：

glDebugMessageEnableAMD parameter <category> has an invalid enum '0x1' (GL_INVALID_ENUM)

自 4.3 版以来，调试消息一直是 OpenGL 的核心。您正在运行 OpenGL 4.1。您需要在有问题的系统上升级 OpenGL。
