It used to work pretty well (3.1.2).

Thanks for the report. This GPU is below the minimum requirements for Blender, so there is no longer support for it. https://www.blender.org/download/requirements/
Installing the latest graphics driver sometimes helps to make such GPUs work, see here for more information. https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

If that doesn't help, you can use previous version: https://www.blender.org/download/previous-versions/

Not true, 3.1 still runs perfectly fine on this "Unsupported" GPU
Why 3.2 wouldn't run, a another dev said this

The GLSL parser seems to handle those qualifiers if the version is 4.2 or larger regardless of the enabled extensions:

(state->AMD_conservative_depth_enable ||
state->ARB_conservative_depth_enable ||
state->is_version(420, 0))) {

If there's a workaround then implement it, don't just brush it off as "It's old and Unsupported"

Plus it runs fine if I override the Mesa driver to use open gl 4.1

@axis You can submit patch to fix issue on not officially supported hardware, it's not that we don't want that HW to run Blender at all. My task is to ensure that this issue is valid for developer to work on it and that also means checking HW requirements. I try to not be strict if I suspect that issue can affect many users, but Ivy bridge architecture is 10 year old HW, (edit) first I meant to say that it's quite far behind haswell which is supported... Turns out I can't do math.

I will merge this task to signal, that there are other users with this issue at least.
