So yep, when starting steam I get this error as in the title. This becomes even more apparent when I try to play e.g. Cubemen 2, who's interface looks very weird, like it's not rendering it properly as shown below:
I'm using an AMD card and Direct Rendering is enabled apparantly according glxinfo:
stanrogo@stanrogo-desktop:~$ glxinfo | grep rendering
direct rendering: Yes
So what could be the problem? I am using AMD proprietary drivers in order to have catalyst control centre to make sure I can have a triple screen set up.
display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6850 X2
OpenGL version string: 4.2.12002 Compatibility Profile Context 9.012
Any help would be much appreciated!
