Summary: KMS/R200: Bad shading in NWN since Mesa rewrite
Product: Mesa
Version: git
Platform: Other

Status: NEW
Severity: normal

Neverwinter Nights with KMS has rendering problems possibly related to other
R200 KMS shading issues reported while before the Radeon rewrite was merged,
Mesa 7.5.2 is fine.
On rv250; characters are almost black except when highlighted with a mouse
over, general scenery appears darker than old reference whilst objects flip to
black as a scene view is rotated.
On R200; characters are very dark but do have some shading compared to rv250,
general scenery tends to flicker madly inverting shading on each tile and even
borders of interface flicker. Note though that am using patch from bug 25544 to
disable texture checking to allow R200 to run but don't think it should be
relevant.
(UMS on both tends to die quickly for other reasons but concentrating on KMS as
the future.)
Attached are comparative screenshots of two scenes with current Mesa git,
libdrm 2.4.18 and Linux 2.6.33.
