Hi I have tested your piglit patch and second version of "Simple reproducer"
from Olivier Fourdan on:

   OpenGL vendor string: Intel Open Source Technology Center
   OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2) 
   OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.8

and 

   OpenGL vendor string: Intel Open Source Technology Center
   OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 620 (Kaby Lake GT2) 
   OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.2.0-devel
(git-04fff21c62)
   with my patch which just fixes unnecessary assert for GL_TEXTURE_2D and
GL_TEXTURE_RECTANGLE targets mismatch.


I could not reproduce the "rendering" issue on  Mesa 17.2.8 and on 18.2.0-devel
versions. I received the identical correct result on both Mesas. So I think
that the "rendering" issue was fixed somewhere between 18.1 and 18.2.0-devel
however Mesa 18.2.0-devel still contains the "assertion" issue which should be
fixed by my patch. 

Note: The first version of "Simple reproducer" from Olivier Fourdan was
producing black screen on both Mesa 17.2.8 and on 18.2.0-devel for me so I
fixed it and it stop to reproduce the "rendering" issue on both Mesas just
"assertion" issue is reproduced.

Сould somebody also check if this "rendering" issue is still reproducable on
Mesa 18.2.0-devel?
