Having started the client today just to test it seems to be working ok after all. The graphical garbage must have just been a glitch.It's the same steps for 4.11 (winetricks dotnet40 win7).
If you haven't already tried it, you could try deleting (and recreating) your prefix. You may also want to try a manual install of dotnet40:
Wine with a bit of extra spice. Contribute to redmcg/wine development by creating an account on GitHub.github.com
I've found 4.11 to be a bit sensitive to other versions of Wine dabbling in the prefix.
For me, yes. I bought ED and Horizons through steam so running it via steamplay is convenient for me.Is there any advantage in using Proton?
