Steam error

This message appears when I try to run a game. The game never appears but apparently is still running

This application requires either the GL_EXT_texture_compression_s3tc, o
r the GL_EXT_texture_compression_dxt1 + GL_ANGLE_texture_compression_dx
t3 + GL_ANGLE_texture_compression_dxt5 OpenGL extensions. Please instal
l S3TC texture support.

It occurs to me that perhaps I should tell you that I am using the open source driver not the proprietary Amd driver.

Found a solution on this page:

Good find Scott. For future ref you can also check out this github link as well and this link about dealing with errors in steam with tumbleweed.
