after updating my htpc this weekend the X server failed to start, with following error in the log:

downgrading to mesa 17.3.0-2 and xorg-server 1.19.5-1 work around the problem temporarily.
This task depends upon

Also happens with mesa 17.3.2-2 (instead of 17.3.1-2).

I found that commenting the following configuration makes xorg-server starting again.
#Section "Extensions"
# Option "Composite" "Disable"

I still have that problem with mesa 17.3.3-2 and xorg-server 1.19.6+13+gd0d1a694f-1. Downgrading the packages still helps, and as reported above so does disabling the composite extensions (which i don't need on the HTPC running Kodi anyways).

Please report this upstream is still present!

Similar issue on ARMv7 after updating today, but no backtrace listed in the log. Downgrading mesa and xorg-server works as workaround. Also found that disabling Xinerama allows xorg-server to start, but clearly without proper screen layout.
