You can test this with viewing "Tetris3D" while playing on a server.
Additionally, please fix the light problem when opening Manialinks after game start before entering any title, see screenshots below. The 3D-Styles are not usable as long as this bug exists.

"Tetris3D" in Storm title, everything is fine.

"Tetris3D" while playing on a Server, all Styles3D are missing.
Additionally, positions/size of the elements seems to be slightly different. Compare the free space below the "Close" label: It is much bigger outside of the Server (first screenshot) than on the server.

"Tetris3D" before entering any title (after launching Maniaplanet), light problem makes Manialink unreadable.
(I already reported this one before, but wanted to add it again as both bugs involve the 3D-Styles.)
