Description
Hello,
"bufferstorage-persistent read client-storage" piglit test fails intermittently with a very low fail-to-pass ratio in Mesa master.
When running "bufferstorage-persistent read client-storage" piglit test during 20/30 minutes in an infinite loop on a Haswell laptop, I got the following error:
$ while (true); do (bin/bufferstorage-persistent read client-storage -auto -fbo | grep -v pass); done Probe [0] failed. Expected: 17.000000 Observed: 0.000000 Probe [1] failed.
