I am using skinning as you can see (#define Skin "Amakrits.vsf").
I didn't anticipate this rendering issue.
Works fine for me on latest Win 10.
Your picture shows you have selected "Don't perform..." option which disables the controls in next group, that is a reason why the controls have different colors.
Did you make any changes in the skin file Amakrits.vsf? My skin looks different (I downloaded it from GitHub few moments ago) and it looks like some tweaks are missing in my case.
Conclusion: this is not an Inno Setup issue, but problem in VCL skinning plugin (try to post your issue here: https://github.com/RRUZ/vcl-styles-plugins/issues), but it looks like it can be improved by tweaking the colors in used .vsf file.
P.S. your script could not be compiled correctly as there were missing Custom Messages and skin / setup initialization functions.

I am creating a program, and I need to display an image and then block input for a few seconds before allowing it again. The problem I am running into is that Delphi is not running the code in order and is executing the Sleep() command before the image command. I have run into this problem before when using Sleep() with a video before displaying a message.
The code looks as follows:
procedure TtForm.WindowsMediaPlayer2Click(ASender: TObject;
nButton, nShiftState: SmallInt; fX, fY: Integer);
Var
buttonSelected: Integer;
begin
buttonSelected := MessageDlg('Well done Monkey!-_-', mtError, mbOKCancel, 0);
if buttonSelected = mrOK then
begin
Pages.Visible := False;
WindowsMediaPlayer2.Visible := False;
imgEroor.BringToFront;
BorderStyle := bsNone;
WindowState := wsMaximized;
imgEroor.Top := 0;
imgEroor.Left := 0;
imgEroor.Width := Screen.Width;
imgEroor.Height := Screen.Height;
imgEroor.BringToFront;
BlockInput(True);
Sleep(10000);
BlockInput(False);
end;
if buttonSelected = mrCancel then
begin
Pages.Visible := False;
WindowsMediaPlayer2.Visible := False;
imgEroor.BringToFront;
BorderStyle := bsNone;
WindowState := wsMaximized;
imgEroor.Top := 0;
imgEroor.Left := 0;
imgEroor.Width := Screen.Width;

I get an EoleSysError exception after executing this line of code:

Spanish: first language.
I select English and no change the language of the language selector.
You have the code already. You just need to make some local variables in the SelectLanguage function global, so they can be used in the LangChange function:
var
LanguageForm: TSetupForm;
SelectLabel: TNewStaticText;
CancelButton: TNewButton;
procedure LangChange(Sender : TObject);
begin
case TNewComboBox(Sender).ItemIndex of
0: { English }
begin
SelectLabel.Caption := 'Select the language to use during the installation:';
CancelButton.Caption := 'Cancel';
LanguageForm.Caption := 'Select setup language';
end;
1: { Czech }
begin
SelectLabel.Caption := 'Zvolte jazyk, kter'+#$FD+' se m'+#$E1+' pou'+#$17E+#$ED+'t b'+#$11B+'hem instalace:';
CancelButton.Caption := 'Storno';
LanguageForm.Caption := 'V'+#$FD+'b'+#$11B+'r jazyka pr'+#$16F+'vodce instalac'+#$ED+'';
end;
end;
end;
In the SelectLanguage, remove these the declarations of local variables:
LanguageForm: TSetupForm;
SelectLabel: TNewStaticText;
CancelButton: TNewButton;
And assign the LangChange event handler:
LangCombo.OnChange := #LangChange;
