Hi,

Recently, Sweet Home 3D users equipped with an AMD graphics card had some hard times with a completely buggy 3D view.
After a while, we discovered that a regression in AMD Adrenalin driver was introduced in version > 22.5.1 and that the origin of this bug came from their implementation of OpenGL glMultTransposeMatrixd function when a non identity matrix is passed in parameter. AMD is aware of this bug and will provide a fix in a coming update, but meanwhile you should avoid this function (for example using the alternative proposed in JoglPipeline class).
Hope this will be useful...
