Mysterious Black Background to Custom Dialog GUI in D3D9 Mode

[thezombiecow]

Further to this thread, I'm having some problems with custom Dialog display. THought I'd better shift discussion to here, since it doesn't seem like a Beginner problem anymore.

I've made a custom GUI for dialog, gDialog and set it to be used in General Options.

Under Direct Draw it displays fine, as intended.

Under D3D9, I'm getting a screenwidth wide black background directly behind the GUI.

The GUI works as intended, and the black disappears when the GUI disappears. I've tried several test games, default games, different GUIs, different image/ colour combinations... all with no change.

Any idea what might be causing it, and if there's a 'do not display big black background' option I've failed to uncheck somewhere? I'm on AGS 3.

I can replicate this problem, it is indeed a bug 3.0.2 SP1.

It is however fixed in the 3.1 RC1, so the fix will be included in the next version once that is released.
