Bug ID: 103762
Summary: [swr] piglit
ext_transform_feedback-immediate-reuse-uniform-buffer
has a ~5% pass rate
Product: Mesa
Version: 17.2
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/swr
Assignee: mesa-dev@lists.freedesktop.org
Reporter: ago...@igalia.com
QA Contact: mesa-dev@lists.freedesktop.org
When running the complete "all" profile in piglit against mesa's swr driver,
ext_transform_feedback-immediate-reuse-uniform-buffer most of the time fails,
but not always.
It seems its pass rate is ~5%.
AFAIK, this is not new for 17.2.x not a recent regression.
A typical piglit report is as follows, although varies from failed run to run:

Environment is an Ubuntu Xenial with custom LLVM packages installed and locally
compiled mesa and mesa dependencies. If needed, I can provide a docker image
with which to test.
