the card, though underpowered, shouldn't have any problems -- as long as the driver and the GL implementations are working. the openchrome driver has a long standing history of issues: glReadPixels() poorly performing or even half-implemented, just to name the first issue that comes to mind. > The result is that some textures (for strings) are rendered as garbage > (eg all strings in test-rotate, test-entry, test-depth etc). it's probably a wrong implementation of mipmapping, if only the text is wrong. you can disable text mipmapping by using: clutter_set_use_mipmapped_text (FALSE); http://www.clutter-project.org/docs/clutter/stable/clutter-General.html#clutter-set-use-mipmapped-text > I had similar issue when trying scrupp (scrupp.sf.net).

Clutter already does slicing by default for every texture that does not fit the texture memory. ciao, Emmanuele. -- Emmanuele Bassi, Intel Open Source Technology Center -- To unsubscribe send a mail to [email protected]
