The Vulkan viewport adds GPU-accelerated surface subdivision. This moves viewport subdivision from CPU to GPU, which improves performance and smooths edges and primitives. Use ⇧ Shift + = and ⇧ Shift + - to toggle subdivision on and off.
For subdivision surfaces, turn the Hulls parameter on and off (in the Display toolbar or Display Options window) to switch between the subdivided surface and the original unsubdivided control cage.

Thank you so much. After I updated to 21.0.440 and restarted the Rocky servers, I ran into the same problem. This fixed it.

copilot can take references from anywhere on the internet
but most of the times when i ask it a Houdini related question, it gives wrong answers even when it takes references from docs

Yeah this is my experience as well. There must be a way to train an AI to properly interpret the docs. Let me ask ChatGPT how to do that.
