Description Gustaw Smolarczyk 2010-03-10 10:59:59 UTC

Automatic mipmap generation (by setting GL_MIPMAP_GENERATION texture parameter to GL_TRUE) with r600_dri is broken when texture dimensions are not powers of two. Level 0 mipmap (original image) is right, but another levels contain garbage. When minification filter is set to some mipmap mode, it clearly shows this issue. Changing texture dimensions to powers of two resolves the problem.

Note: classic r600 driver has been abandoned.
Please use r600g (gallium driver) instead.

Is this still an issue with a newer driver/kernel?

The classic r600 driver has been abandoned long ago.
It was replaced by the Gallium driver r600g.

If you have issues with r600g please file a new bug report with component Drivers/Gallium/r600

Thanks.
