I'm having the same issue with Ubuntu Focal, kernel 5.4.0-40-generic and latest Nvidia 450.57 from https://launchpad.net/~graphics- drivers/+archive/ubuntu/ppa.
I started having this issue when I update Chrome **after** 81.0.4044.138. Up to this version, things work. From this Chrome version on, whenever I open any OpenGL site (eg: onshape.com), everything freezes for a good 30s, I get a message on "OpenGL not working" from the website, and kernel spits this: [ 80.762915] NVRM: GPU at PCI:0000:09:00: GPU-824bae61-b6cb-f859-5c4b-531553afa61b [ 80.762918] NVRM: GPU Board Serial Number: [ 80.762922] NVRM: Xid (PCI:0000:09:00): 31, pid=5024, Ch 00000016, intr 00000000.

I'm using the tested one "nvidia-driver-435", installed via the GUI tool. Could you report this to Nvidia please ?
