Steam – Cities: Skyline fails to generate correct menu and crashes on exit

I just installed Cities Skylines on my linux mint 17 os which includes a R7 260X Radeon graphics card.

The game fails to launch with an appropriate menu screen as depicted in the screen shot provided. The image of the menu is centered at at the top right of my screen, while the menu clickable buttons are still centered in the screen. The game freezes when I attempted to click 'Exit Game.'

Above are the error messages from the terminal while steam was running. I investigated the error 'ERROR: ld.so: object '/home/root/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.' I found a discussion of this error on ArchLinux which suggested the following terminal 'find ~/.steam/root/ ( -name "libgcc_s.so*" -o -name "libstdc++.so*" -o -name "libxcb.so*" ) -print -delete
' but was unsuccessful.

What must be done to force this game to run correctly on linux? This game is supposed to be linux native.

Update

Disabling Steam overlay did not fix the problem.

I uninstalled the repo steam and installed latest deb steam, that did not work as well.
