are you sure you are using the help-patches from 0.90 ?? there should be 
a lot in there (like mentioning the rectangle stuff)

even under linux rectangle textures work as they should (e.g.: no 
repetition)
BUT: if your gfx-card does support rectangle-textures AND gem has been 
compiled apropriately (e.g. by using nvidia's openGL-header files) 
rectangle-textures will be used for non-2^n images. (meaning: no 
"repeat", ...)
if one of these conditions is not true, a tricky hack is used to display 
  the non-2^n images as if they were 2^n-sized (the trick is using 
sub-textures) which gives some other problems (esp. performance 
penalties); as this is basically "normalized" textures, wrapping will work.

easy, isn't it ?
