this definitely is a graphics issue.
if u got no error messages while winetricking d3dx9, then it must be a graphics driver issue, or a graphics related one.
do you use a composition window manager (which requires OpenGL) such as Compiz or KWin?
if you do so, try disabling the 3D or animation effects before launching game.
I use KDE 4.8.3 and I have no problems keeping Compiz-fusion enabled (I use Sabayon Linux which is a Gentoo fork) while I play LoL.
