This issue still seems to exist in the latest revision of the 1.7. It's not really serious, just a kind of annoying inconsistency between D3D and OpenGL drivers.

If the format for addRenderTargetTexture() is not given (ECF_UNKNOWN), in D3D it uses the same format as screen buffer. But in OpenGL it ...

Not probably a bug, but I just wanted to confirm whether it's intentional that the matrix multiplication is done in the wrong order. For example, if we have a simple multiplication like this:

matrix4 M1, M2, M3;
...
M3 = M1*M2;

The result is not M1*M2, but M2*M1. This is assuming that the ...

For example if you have a material set with colormask ECP_ALPHA, and you call beginScene(), setRenderTarget() etc, which by default clear the buffer, they will only clear the alpha channel.

Perhaps this is desired behavior, but even if you set a new material with colormask ECP_ALL before the call ...

The change I have made is that those functions are now no longer called in the constructor - where they _never had_ worked - so nothing gets broken that did work before.

You can't say they never worked. Even though virtual calls in constructor aren't recommended, their behavior is still well ...

Removing virtual in a base-class while keeping the function-name does actually sound like a pretty bad API change to me. You wouldn't even get a compile warning about stuff no longer working.
That's already the case. You gotta assume that all the classes that override addChild() or ...

But in short - if that element really needs the virtual addChild call then it already didn't work before. The reason for the change was that virtual functions are _not_ called in constructors.
I agree. I was just thinking it might be better to change addChild into a non-virtual function. They way ...

I see that there was a change made so that IGUIElement constructor doesn't call the virtual addChild() method anymore. This breaks components like CGUIPanel (used in GUIEditor) which requires that children are always ...
