Pretty much everything.
Installation: no problems at all.
Launcher/patcher works with some display problems (see below) and a crash.
Beta activation works.
Settings works (tried different settings on about half of the available options).
Internet multiplayer works wonderfully. I played the game for hours without problems.
What does not
The game does not shut down properly. It appears to, but stays active if you check "ps -e", for example. It's easily killable with kill/killall, or by running "wineserver -k" to kill all the wine stuff.
Lighting effects do not work. Shadows jitter around, and sometimes things are much darker than they should be. If you turn off lighting effects, everything looks fine.
Music can skip/stutter a little while loading.
Frame rate is so-so, but my graphics card, as well as the rest of my computer, is a bit old -- built it at the end of 2007 (for Hellgate: London, actually). I guess the Wine overhead and Gnome Shell compositing take their toll as well.
What was not tested
Of course, I haven't finished the game. There might be problematic events, shaders or special cases waiting for me down the line.
Tested on a clean Wine install. The launcher was covered by a black box. Moving the black box (I did it with Alt-click/drag) reveals the launcher. Really weird. While patching, the launcher crashed once. Starting it again, it quickly verified the download and successfully applied the patch. Frame rate is so-so, but my graphics card is a bit old (fan-less GeForce 8600GTS bought in 2007). I guess the Wine overhead and Gnome Shell compositing take their toll as well. Played my first game for hours. No crashes or obvious problems.

It appears the game doesn't always shut down properly. For the all versions, this will waste RAM (and possibly CPU time). For the Steam version, this will also prevent cloud syncs, and you will not be able to re-launch Torchlight 2 until the old process is gone.
Use killall Torchlight2.exe2 to force-kill it. In my experience, this has no negative effects (if you do it after trying to shut down the game properly first).
