htt p://bugs.freedesktop.org/show_bug.cgi?id=13508 ------- Comment #1 from nian.wuintel.com 2007-12-03 23:52 PST ------- Created an attachment (id=12924) --> (http://bugs.freedesktop.org/attachment.cgi?id =12924&action=view) test case The test case draws a 32x32 texture image, but only 32x16 size is drawn with i915 driver. With i965 driver or Mesa 7.0.2, the texture is applied correct. -- Configure bugmail: h ttp://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------ ------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

htt p://bugs.freedesktop.org/show_bug.cgi?id=13508 ------- Comment #2 from srolandtungstengraphics.com 2007-12-04 05:32 PST ------- Note that you're requesting an internalFormat of 1, which is GL_LUMINANCE, not LUMINANCE_ALPHA. There's nothing wrong with that, but the bug could be rather with this internalFormat. Not sure what's wrong though, maybe some pitch alignment problem (in this case related to the reported mipmap bugs possibly). -- Configure bugmail: h ttp://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------ ------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

I never suggested it has something to do with the alpha channel, rather that it might not be the texture format which matters here but that the internalFormat of GL_LUMINANCE might be the culprit instead. -- Configure bugmail: h ttp://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------ ------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
