Operating system: Windows 10
Graphics card: GeForce RTX 2070 Super
Broken: (example: 2.81)
Short description of error
When setting the system to use OptiX to render and start the rendering process, no progress is made. Trying to stop the rendering/close the pop-up rendering window leads to strange GUI behavior and no new rendering can be started. Closing Blender hangs and needs to be killed from Task Manager.
Rendering with CUDA works as expected.
I'm using the latest NVidia driver (441.20), 8GB GDDR, 32GB RAM, Intel Core i7-5930K
Exact steps for others to reproduce the error
Based on the default startup with rendering in Cycles and GPU as well as setting OptiX as cycles engine the error already is reproduced.
