System Information
Operating system: Linux-5.8.6-1-MANJARO-x86_64-with-glibc2.29 64 Bits
Graphics card: GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 450.66

Blender Version
Broken: version: 2.90.0, branch: makepkg (modified), commit date: 2020-08-31 11:26, hash: 0330d1af29
Worked: (newest version of Blender that worked as expected)

Short description of error
Attempting to use the shader viewport while using Eevee, using my GPU, makes my system go into slow motion until Blender is closed.
It didn't used to do this for me before until just recently. I also attempted to download older Blender versions to see if it would make a difference but it won't fix itself for some reason.
(My main install of Blender is from Manjaro's repo)
I have no idea what could be causing it.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Using this .blend file of an icecream cone, just clicking on the shader viewport button causes this to happen.

IceCream Cone.blend

I also used this free 4K HDRI but it refuses to show up for whatever reason I don't understand. Removing it didn't make a difference.

I cannot reproduce the problem here.
Try running blender from the command line with the --debug-gpu option.
After trigger the bug, you can copy information from the command line into a .txt file and attach it here.

Blender Debug-gpu.log

Also, it seems that after waiting a bit, my system becomes responsive again but attempting to interact with the render window causes the system to slo-mo lag again for a while and happens every time.

There is no error or warning message, I'm not sure if these messages will help much.

Have you checked if the drivers are up to date?

To upgrade to the latest driver, see here for more information: https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

Can you try build from https://builder.blender.org/download/ ?

Also happened with that version.
Starting to think Nvidia's latest driver might just be bad, because this didn't start happening until recently.

Scratch that, rolling back didn't fix the problem either.

I just tried to do it in Windows on the same hardware (separate drive) without any issue.
I have no idea what's going on here. x_x

Hi @Neko-san, is this still a problem for you in recent releases like 2.93.0 and when using recent nVidia drivers (version 460 onwards)?

Sorry for the silence; I was hospitalized recently

It had turned out to be a hardware issue; I had my GPU replaced by EVGA and the issue no longer occured on the new card.

I appreciate the interest in helping solve the issue though, thanks.
