Blender Version
Broken: Blender 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd7, MantaflowTest.blend

Short description of error
During rendering I have Cuda error in Cycles, the same happens during rendering animation.
If I press render animation again, I get an error about the launch and render do not start.
When I switch to use CPU each frame and all animation are rendered without a problem.
Few times during rendering I experienced that blander full crashed and disappeared
Before in blender 2.8, 2.81, 2.81a such error never happened

Exact steps for others to reproduce the error
Well steps lool like this that right now I cant render this file while using GPU to render

This is a known limitation of graphics drivers, see here:
https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html#the-nvidia-opengl-driver-lost-connection-with-the-display-driver

It will happen especially with volumes or refractions with a high number of bounces.

Possible solutions are reducing bounces or volume steps, changing the driver timeout limit, or using a newer generation graphics card which no longer has the timeout problem.
