1 is a known issue and will probably get fixed eventually, tho it might be an amd thing. The loading screens are getting better with every patch. I don't really get 10 tho, all files are under /

looks more like Driver/Hardware problems with your Linux installation, these have nothing todo with Steam.. and btw, Valve's hardware???

edit:
try disable compiz when playing games btw

Your problem is that you have an AMD card.

Rule #1 for gaming on Linux: Have a Nvidia card.

I wish it were different. Hopefully it will be different in the not too distant future.
But in the past AMD never delivered good drivers for Linux.

aticonfig --odgt

in the console.
