When using the nvidia-driver-361.* I am unable to start some GTK(?) applications, they crash with a "Segmentation fault". Some example programs include: - nvidia-settings - virt-manager $ nvidia-settings Segmentation fault $ gdb nvidia-settings GNU gdb (Gentoo 7.10.1 vanilla) 7.10.1 Copyright (C) 2015 Free Software Foundation, Inc.

I can even switch back to the nvidia implementation and it stays functional (until I restart X). My secondary monitory is running off the internal GPU (intel). I am not sure if this can be the issue, but I would assume it's not very common. Reproducible: Always Steps to Reproduce: 1.

I'd be curious to see more information in the backtrace. Could you compile libepoxy with debugging symbols? That is, add -O0 -g3 to your CFLAGS and recompile it.
