Product: Mesa Version: CVS Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Drivers/DRI/Unichrome AssignedTo: dri...@li... ReportedBy: uni...@sh... There seems to be depth buffer issues with transparent objects with the Unichrome. Although the objects are not visible against the background since they are transparent, they seem to somehow obscure other objects. Perhaps objects that get drawn later. To reproduce: Launch tucracer. At the beginning of the first lap, Tux will suddenly disappear, and then reappear again. Also at the start of the second level, The starting banner seems to be obscured by a transparent object. -- Configure bugmail: https://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. |

I vaguely remember fixing a related problem in the Savage driver once. On the Savage there is a bit that says "write Z after alpha test". If you don't set that bit then fragments that fail the alpha test still write a Z value so that they "obscure" stuff that is drawn later. -- Configure bugmail: https://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. |
