Hi Guys !

I would like to come back on this ticket because, for me, the problem I
reported is completely fixed by the patch George Kyriazis provided. However, I
noticed his patch is not applied to anything after 17.1.3. For example the
latest release exactly reproduces the original issue.

Anyhow, I'm not sure what process must run before this fix can be applied but I
can report that the issue is completely resolved when George's patch is applied
to revision 89d4008ac85714bab8c49974377fd37970f6d66a - along with the patch set
below. I'm not sure on what branch this revision is attached as it is no longer
on the master/best-so-far branch. 

It would be great to have this patch on 17.2!

Patch set (https://github.com/trevorsandy/osmesa-install):
# add_pi.patch \
# gallium-once-flag.patch \
# gallium-osmesa-threadsafe.patch \
# glapi-getproc-mangled.patch \
# install-GL-headers.patch \
# lp_scene-safe.patch \
# mesa-glversion-override.patch \
# osmesa-gallium-driver.patch \
# redefinition-of-typedef-nirshader.patch \
# scons25.patch \
# scons-llvm-3-9-libs.patch \
# swr-sched.patch \
# msys2_scons_fix.patch \
# 0001-mingw-fixes.patch - George's patch is not in my repo - sorry:(

I can successfully run a quick osmesa rendering test for swr, lvmpipe and
softpipe driver settings with the following MSYS2/MinGW DevEnv settings:
