Is this a bug?
Something's failing bigtime - GL can't allocate a texture or other
buffer. Not really enough info here, but perhaps something interesting
in dmesg after this happens. I'd recommend using xf86-video-nouveau
though, instead of modesetting, since it doesn't involve trying to use
GL all the time.

xserver-xorg-video-nouveau is already the newest version (1:1.0.15-3).

Little hope of reclocking becoming available for GM20x and newer GPUs as firmware now needs to be signed by NVIDIA to have the necessary access.
Is that why I get this:
# cat /sys/kernel/debug/dri/0/pstate cat:
/sys/kernel/debug/dri/0/pstate: No such device
Can I see the current clocking with nouveau?
Everything should at least be readable.
