(Get the code!)
This has to do with how the OSD is created, in a sort of pseudo transparency. It takes a screenshot of the area under where the OSD will appear and then sets that as its background. Then, any changes underneath the OSD, such as window changes or typing text, will not appear until it goes away, since the screenshot is not dynamically updated as things underneath it are updated.
I think KDE 4.0 hopes to address this, and dynamic transparency is also a major goal of the XGL/AIGLX/Compiz direction we're seeing in linux. Until that happens, I'm not sure that the transparency thing will be resolved.
You mentioned that the problem appeared in the update from 1.4.4 to 1.4.3 Could you please explain this a bit more? Thanks.
