Hey blaat,
Still being plagued? I am having the same issue on Arch Linux x64 with an nvidia card.
Rust normally keeps it's player.log in one of the sub-folders of '~/.config/unity3d/Facepunch Studios'.
There used to be a '-logfile' or '-logFile' option in Legacy to output a bit more info but I don't know the state of this option in Experimental.
However in Steam you can set the launch option of Rust to something like this to save the console log to a file: '%command% > ~/rust.log'.
Here is a link to my output: http://pastebin.com/4n9SB2dY
I suspect this is a CoherentUI compatibility issue with linux but the warnings and errors I get are like this:
Code:
WARNING: Shader Unsupported: 'Hidden/NoiseAndGrainDX11' - Setting to default shader.
[Coherent UI] (Warning) PID: 29188 | 29206 15:29:17.957771 [29188:29206:WARNING:proxy_service.cc(888)] PAC support disabled because there is no system implementation

You can also use this command in a terminal to quickly scan your files for errors or warnings: cat ~/rust.log | egrep -w 'WARNING|ERROR|Warning'
Hope this helps, let me know what you come up with.
