So I'm using Godot game engine on Ubuntu, but I'm having a problem with OpenGL, google led me to this issue:
https://github.com/godotengine/godot/issues/8700
which confirmed that it's a driver issue and is fixed in mesa 17.3.1.
But I haven't figure out how to install it, I tried:
sudo add-apt-repository ppa:ubuntu-x-swat/updates
then
sudo apt update && sudo apt dist-upgrade
but now I'm only getting
OpenGL version string: 3.0 Mesa 17.2.4
I've compiled 17.3.1 from source, but I didn't figure how to install it.
The PPA you've added has this in its description:
...and indeed xorg-edgers PPA contains mesa 17.3.1 for 16.04.
You can add it with
sudo add-apt-repository ppa:xorg-edgers/ppa
.
