Bug ID: 102581 Summary: 3D texture mipmapping broken Product: Mesa Version: 17.1 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: mail@felix-potthast.de QA Contact: dri-devel@lists.freedesktop.org
Created attachment 134041 --> https://bugs.freedesktop.org/attachment.cgi?id=134041&action=edit Screenshot comparison
When trying to display https://www.shadertoy.com/view/4llcR4 i get artifacts near horizon due to mipmapping (artifacts are absent with mipmapping disabled). It works as expected with the proprietary driver (under Windows) on the same machine. See attached image for Screenshot comparison.
So either mipmap generation or display seems to be erroneous for 3D textures.
My card is AMD Radeon HD 7870.
