English is not my native language. I'm sorry if I don't make myself clear. But I'll try

When I arrived at honeybee inn, some thing cought my eye. In the !@$# Room, the "ghost" Cloud isn't transparant as it should be. Also light effect from the background that should be fading from dark to bright aren't there. Light's are always bright and not fading.
This happens only if I use 3d hardware acceleration. In software mode these problems don't occur. I have used the 1.02 patch.

Here you can see the "ghost" cloud. Not transparent as it should be.

This is the software version. Transparant. The color of the room is different from the above. Don't know why.

The textures around the doors are strangely lighter plus the shiny light on the logo on the floor aren't twinkling.

This is like it should be
Is this a known problem? And if so, is there a solution for this?
