Summary: Black line in Lightsmark with Z compression enabled (RV530) Product: Mesa Version: git Platform: Other URL: http://dee.cz/lightsmark/Lightsmark2008.2.0.tar.bz2 OS/Version: All Status: NEW Severity: minor Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: drakkk@centrum.cz
After recent zbuffer compression rework Lightsmark is the only remaining app I've tested which is still not working properly here on RV530. There is a thick black line across the screen in some scenes, particularly: "no radiosity","soft shadows", "penumbra shadows" and the last scene. Maybe this is a known issue and there are many open bugs about HyperZ, however according to db299a9f8244d53d9041fcdbd396a77ebe1f9e3e comment RV530 should just work. So I'm reporting it isn't. Also this is not a regression, it was much worse before and this is the only remaining issue here.
To be sure this isn't HiZ issue I've changed line 367 in r300_chipset.c to "caps->hiz_ram = 0;" and it haven't changed anything. r300: AA compression: NO, Z compression: YES, HiZ: NO
