Description Béla Gyebrószki 2015-07-11 11:34:17 UTC

Created attachment 117057 [details]
screenshot, comparison (nouveau vs. nvidia)

The application runs natively on Linux, I tested the demo version on Steam.
The demo contains some example sceneries, all of them have the same problem: terrain objects (rocks, vegetation) are rendered properly, but ground textures are black.

Disabling shader optimization doesn't help.
Ground looks OK with the llvmpipe driver/ Nvidia binary drivers.
Tested and reproduced in Mesa 10.1 and 10.4 as well.

Reproduced with GT215. However GF108 shows different artifacts (some white dots in the background).

Comment 2 Béla Gyebrószki 2016-06-05 15:52:03 UTC

The problem is still present when using the original trace file in the bug description in current Mesa.
However, the application has been upgraded on Steam (both the engine and the samples) and I can't reproduce the problem with the current application version.
