LIBGL_DRI3_DISABLE=1 not needed anymore (?)

[Mikhail Novosyolov]

From /usr/bin/chromium-browser:
# Work around crbug.com/415681
lsmod |grep ^i915\ >/dev/null && export LIBGL_DRI3_DISABLE=1

As written on the bug page, it seems to be not an issue anymore. I commented out that line, and it seems that Chromium works well.

I run Chromium with custom flags, from chrome://gpu:

This is not in the official packages from the ubuntu archive.
Please report the issue at https://github.com/saiarcot895/chromium-ubuntu-build/issues. Thanks!
