Vulkan freeze on calling vkDestroyDevice on nvidia closed drivers.

It affects all applications.

Driver version 495.44 from package nvidia-dkms. GeForce 1070 GTX card. I posted this on nvidia forums but no anwsers. It's been broken like this since the last driver version. Any idea what could be going on? (yes I know nvidia bad, my next card is definitely AMD).

There's technically a newer driver version, maybe fixed there?

Same problem on version 495.46.

Re: Vulkan freeze on calling vkDestroyDevice on nvidia closed drivers.

I traced the problem to using __GL_THREADED_OPTIMIZATIONS. I guess it's not a good idea to blanket enable that everywhere.

Interesting.
I wonder what __GL_THREADED_OPTIMIZATIONS has to do with Vulkan drivers.

Re: Vulkan freeze on calling vkDestroyDevice on nvidia closed drivers.

I have the same thing happening to me without using the __GL_THREADED_OPTIMIZATIONS environment variable, in many games.

DotA2 Vulkan, for instance, has been freezing at shutdown for a while (a month?  maybe more -- I have to kill it externally).  Using OpenGL to run the game allows normal shutdown.

nvidia: 495.46-6 on RTX 3080Ti.

Re: Vulkan freeze on calling vkDestroyDevice on nvidia closed drivers.

It's very possible the game sets that environment variable for itself, as it used to be a common perf optimisation for certain OpenGL use cases. To check you can do

tr '\0' '\n' < /proc/$(pidof dota)/environ

replace the dota with the actual process name, not sure what it uses here.
