OK, what's happening is that the icon definition isn't running your
Exec through a full shell. Which isn't unreasonable.

What you need is a shell wrapper. Call it, say, /usr/local/bin/cr:

#! /bin/bash

export MESA_EXTENSION_OVERRIDE=-GL_MESA_framebuffer_flip_y
exec chromium-browser "$@"

(the "$@" effectively means "pass on any parameters you received")

and chmod it 755.

Then turn the .desktop file to point at that:

Exec=/usr/local/bin/cr %U
