Steam window not rendered correctly on Ubuntu

[MAX]

Hello, I installed Steam client on Ubuntu 17.04 and stuck with the problem since yesterday. The screenshot is at the link below.

• The 'control' inside that window seems to be functional. I click on the area where 'close' button supposed to be and the steam is closed as well.
  
• The content displayed within that area depends on whatever on the screen at the moment I started steam.
  
• When I drag the steam 'window', the content stays with the window as well. Here[ibb.co] is the screenshot after I move the window to a different position.

Already:

• Update NVidia Driver
  
• Install driver download from Nvidia Website
  
• Install driver from APT
  
• Uninstall and Install Nvidia Driver
  
• Uninstall, wipe and install Steam
  
• Install steam from APT
  
• Install steam from the official website.
  
• Google and desperately tried numbers of 'fixes' that didn't work.
