11.2.0
Product: Mesa
Version: 11.0
Hardware: x86 (IA32)
OS: Linux (All)
Status: NEW
Severity: normal

No artefacts when rendering FRONT and BACK
There are bad artefacts when rendering via an FBO to FRONT with a blit. These
are absent when rendering to both FRONT_AND_BACK buffers with a buffer swap.
Environment:
Linux Mint 17 (Linux 3.13.0-24-generic)
Mesa 11.2.0 (via oibaf)
HD6000 GPU
Attached are two executables one with FBO rendering one without. The Mesa Intel
linker takes two minutes to link so be patient.
The very same executables work just fine with an Nvida GPU.
