Public bug reported:
tl;dr: it would be nice to be able to set environment variable on a per-
snap basis.
I ran into this need when trying to workaround a chrome/chromium bug [1]
where one needs to export MESA_GLSL_CACHE_DISABLE=true when starting the
browser to have the GPU sandbox working. It's doable this way:
MESA_GLSL_CACHE_DISABLE=true chromium
but is not convenient since more often than not, chromium is started by
clicking the icon. Editing the .desktop file would surely work too but
is not very user friendly. I'm also not sure if the .desktop file is not
refreshed along with the snap.
