Users with optimus systems are reporting that
many games fail to run in libdrm-intel is upgraded
from 2.4.56 to 2.4.58. (And, downgrading to 2.4.56
fixes the issue.

Steam bug:

Debian bug:

I don't have hardware to confirm this issue.

I notice that between 2.4.56 and 2.4.58 libdrm changed
some symbol visibility settings.
