Divinity: Original Sin [Official Site] is one game that the stable open source Mesa drivers currently cannot run without hacks, but it looks like the Mesa team has been testing it.
Just today a commit was sent in to Mesa which mentioned "drirc: Allow extension midshader for Divinity: Original Sin (EE)". It's interesting to see game-specific changes like this, as some games will sadly need them.
You can see the commit here, which has already landed in Mesa-git. You can see the actual bug report about it here.
Hopefully with this patch landed, it means more people can enjoy another highly rated Linux-native game on open source drivers. It might still need other hacks to run, as previously it needed more than one change.
While this is only changing a config file to have this game-specific change in by default, it's still nice that users don't have to look up what to do to get it working.
I cannot test it personally, as I don't have an AMD card to test with. Article taken from GamingOnLinux.com.

Quoting: ShmerlThank you for the clarification Shmerl.Quoting: Joeyboots80I look forward to playing this as I have had it for over a year but have nt tried it yet due to the fact that I use mesa. Thanks for this news Liam. ^_^
This won't solve the issue fully. The workaround for Mesa helps, so you can as well apply it today.

Just to clarify:
You can play Divinity: Original Sin right now with stable Mesa, and you don't need any patches to mesa to get it running.
All you need is to set the environment variable allow_glsl_extension_directive_midshader=true, and you'll need to LD_PRELOAD the preload-shim linked in the upstream bug report (link.
Step by step guide:
1) Download the source for the LD_PRELOAD shim
2) Compile it using the command given inside the just downloaded patch file. This will give you a divos-hack.so file.
3) Copy the just created divos-hack.so file to your Divinity: Original Sin game folder (the subfolder called game, within the install path)
4) now, from said game folder, run Divinity using the following command:
Edit:
Thanks, cRaZy-bisCuiT, for bringing this up. The instructions above are for the GoG version of PoE. For Steam multiplayer and overlay support you'll need to preserve Steam's LD_PRELOAD settings when launching the game, meaning that you'll have to run it through Steam. To do this, first create the divos-hack.so file as above, and then go to the preferences of Divinity: OS in your Steam Library (right click on the entry -> Preferences), and open the "Set Launch Options" dialogue. There, put the following:
It might be necessary to give the full path to divos-hack.so for Steam (I haven't tested it, as I bought the game on GoG).

I also recommend setting this for the game, otherwise it will clutter your $HOME:
HOME=${HOME}/.local/share

Quoting: soulsourceJust to clarify:This is my point, some sort of hacks are needed. This is one step towards letting it run without manual work.

After all it's just a new default entry for .drirc o_O I don't get the hype.

Quoting: liamdaweThe point is as stated, not making users resort to hacks to get a game working on open source drivers.I know ... but changing a configuration value should not be called "hack" IMHO. DriConf isn't a driver hacking tool either, it's a configuration utility.

Quoting: crt0megaLet's not get pedantic about semantics. The end result is the same, users don't have to fuss around and search around for solutions.Quoting: liamdaweThe point is as stated, not making users resort to hacks to get a game working on open source drivers.I know ... but changing a configuration value should not be called "hack" IMHO.

Quoting: liamdaweThe end result is the same, users don't have to fuss around and search around for solutions.I agree. Let's hope Larian makes the next step which renders this hack unnecessary.
Edit: About unnecessary things – was it really necessary to drag this discussion to Twitter and even change my message by cherry-picking and ignoring the term "IMHO"? :|
