Description Mark Janes 2016-05-06 15:41:07 UTC 
This failure mode is not easy to reproduce, but it causes intermittent false positives in the CI:

/tmp/build_root/m64/opt/deqp/modules/gles31/deqp-gles31 --deqp-case=dEQP-GLES31.functional.program_interface_query.uniform.array_stride.default_block.aggregates.ivec3_array_struct --deqp-log-images=disable --deqp-gl-config-name=rgba8888d24s8 --deqp-surface-width=400 --deqp-surface-height=300 --deqp-visibility=hidden

Comment 1 Mark Janes 2016-05-06 15:51:35 UTC 
A quick survey of recent test results shows 8/8 failures to occur on BDWGT2.
Comment 2 Mark Janes 2016-05-19 22:44:40 UTC 
The first error printed does *not* appear for passing tests:

Warning: Unable to create native OpenGL ES 3.1 context, will use wrapper context.

Hi, Makr
I've tried to reproduce the issue on BDWGT2 (Intel® HD Graphics 5500) with Ubuntu 18.04 and Kernel 5.0.1 with mesa 18.2.2 and latest master versions - test passed.
As I see,  test added to the CI suite.
I think we can close the ticket.
Comment 4 Mark Janes 2019-03-12 15:13:40 UTC 
Agreed.  Thank you for verifying.
