test result of fbo
bisect? (In reply to comment #3) > bisect? But I find it failed from 20080826, the day GL_EXT_framebuffer_object was supported. Before that it was not supported. OK, we don't really expect bug reports for always-failing testcases at this point -- our priority is regressions and improving issues that are impacting applications. This was a bug in the testcase when handling an unsupported framebuffer in a previous test. Yet another reason why you should never build tests that test more than one thing at a time. commit 35122d69307f0b9c88bc143715f616be80ac5cae Author: Eric Anholt <eric@anholt.net> Date: Fri Sep 24 11:28:49 2010 -0700 glean/tfbo: Properly clean up when the driver reports unsupported. Fixes spurious test failures on the intel driver. It still fails on Pineview now with the same error info as following.

some more info is I tested it with both the glean source contained in piglit test and the glean source from glean.git.sourceforge.net. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
