Priority: medium Bug ID: 69081 Assignee: dri-devel@lists.freedesktop.org Summary: Incorrect rendering of textures Severity: normal Classification: Unclassified OS: Linux (All) Reporter: j.suarez.agapito@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa

First of all, thank you very much for the effort applied on the radeonsi driver. It's getting a nice shape quite quickly.

I have noticed some problems with the rendering on some games, such as Killing Floor ("KF") and Crusader Kings II ("CK II").

The problem consists in that certain textures appear as black. This is not related to a dxtn problem, but rather it seems to be related to the way the (global?, in the case of CK II) illumination of the scene is applied. I have made this conclusion based on the fact that although on CK II all the terrain textures show a black colour (check the screenshots attached below, one of them with radeonsi, the other one with fglrx), on KF sometimes a texture is shown correct but a few steps ahead it is shown black. This usually happens when there is something blocking a source of illumination (check the two screenshots attached below, where one is taken like just one step ahead or behind of the other screenshot, both with radeonsi).

I believe the bugs on both games are the same or at least related and thus I am only opening a bug report.

My PC specs are as follows (taken from steam's system info):

The GPU is a Radeon HD 7870. VRAM is 2 GB. Mesa's version is shown above (9.3 git 505fad0), plus llvm's version is 3.3-5ubuntu1~r~gd, installed from oibaf's ppa.

I am also attaching the shader dumps from CK II and KF (in the map in which the screenshots were taken and having passed where the bug shows).

Please, if any other information is needed, just let me know.
