Can you try to narrow down the list of upgraded packaged that caused this?

I haven't seen these warnings before. I guess that something broke within the 
nvidia driver.

Also the backtrace points to the nvidia glcore libs.

Mmmh, this is the kernel from stable running in stretch, that's not really 
expected, you might want to switch to the kernel in stretch.

Anyway, assuming that the problem is in the nvidia driver, if the driver was 
updated, the kernel module needs to be reloaded, which means that you need to 
reboot the machine. If you haven't done so, please check if the problem solves 
by itself after a reboot.

If that's not good, there is newer nvidia driver in sid, you might might want 
to try it. Also, it might be a good idea to test downgrading the nvidia 
drivers to the last known to work version, you can use 
http://snapshots.debian.org to search for this.

We might need to reassign this issue to the nvidia developers depending on 
your tests results.

Happy hacking,
