Bug ID: 89026
Summary: Renderbuffer layered state used for framebuffer
completeness test
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
Assignee: mesa-dev@lists.freedesktop.org
Reporter: lankyle...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org

Patch
When binding a layered texture to a framebuffer, the framebuffer is marked as
layered. When a renderbuffer is bound to the same attachment point, it replaces
the texture, but mesa doesn't clear the layered state. When checking for
framebuffer completeness, the left over layered state is used, even though
renderbuffers don't have layered state. This can result in framebuffer
incompleteness with GL_FRAMEBUFFER_INCOMPLETE_LAYER_TARGETS when there are no
layered attachment points.
This occurs on the 10.4 branch at 54da987baec25fbaf6975c93f197ddbfe65a303c and
the master branch at 49299ef6fa0cf88e7101512400a4e74efa300941.
