System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 466.11

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: 2.91 (it definitely never happens in 2.91, at least on my machine)

Seems like this broke between ba740ad2ab (good) and 977ef04746 (bad)

Short description of error
When hiding/showing objects quickly in the viewport there's a high probability that the viewport rendering will crash with the following error:

CUDA_ERROR_ILLEGAL_ADDRESS in cuStreamSynchronize(cuda_stream[thread_index]) (device_optix.cpp:816)

the exact function and line reported in this error varies a bit.

Exact steps for others to reproduce the error

Open "The Junk Shop" from Blender's official demo files (I've had more luck reproducing it with heavier scenes).
Go to rendered view.
Click the eye icon in the outliner to hide the Girl collection.
Click the eye icon again to show the Girl collection.
Repeat step 3 and 4 in varying speeds until the viewport render crashes.

Note:
I'm aware this might seem like a non-issue when following the repro steps, but this can and does happen even when hiding/showing an object only once, depending on the scene.

Yes I can confirm this. Was already noticing this in the 2.92 alpha or beta which I started using because of the new ambient occlusion support in Optix (don't know if that has to do with the crashes tho). Didn't really know how to report this in a good way so I never did, instead I got it into my muscle memory to pause then render whenever I was gonna hide or show something. Would be nice with a proper fix tho :)
