Hi, Michel, I think I may have a lead on the blending problems with the r200 DRI driver. The problem seems to go away if I apply the attached patch to Mesa-6.5.3. This seems to work when tested under gcc 4.1.3 or 4.2 (20070528). Open questions include: - Is the "0" usage in "asm" statements

Bug#423739: update on banding

2007-06-01 Thread Dan Torop
As an update to the prior report... In the current "experimental" version of mesa-dri (6.5.3-1), the driver shows the same symptons as my home-compiled version. That is, when using the r200 DRI driver, the test program shows a solid color (see attached screenshot) -- rather than the desirable 50

Hi, Michael, Thanks for the questions and information... Responses follow: This only happens with glBitmap(). I don't see it with either glDrawPixels (GL_RGB or GL_RGBA format, with GL_UNSIGNED_BYTE data) or GL_QUADS (or equivalent glRect). I saw banding when I tried 6.5.2-4 Mesa with direct
