Description of problem:
When visiting any website that uses any kind of resources (CPU, GPU, RAM, etc.) for rendering, the web browser crashes and throws an error in the console, displaying the "Aw, Snap!" error in-window. 

Version-Release number of selected component (if applicable):
chromium: 78.0.3904.97-1.fc32.x86_64
google-chrome-stable: 78.0.3904.97-1.x86_64
google-chrome-beta: 79.0.3945.36-1.x86_64
google-chrome-unstable: 80.0.3964.0-1.x86_64
kernel: 5.4.0-0.rc7.git1.2.fc32.x86_64

How reproducible:
Reproducible in a blank profile (tested on all three browsers) on the kernel version supplied.

Steps to Reproduce:
1. Install any of the above browsers (chromium from rawhide, google-chrome-* from Google's repository)
2. Visit any website which loads actual resources like images, scripts, or styles (I tried Gmail, Reddit, Phoronix, LWN, and many other webpages)
3. Observe the result in the console of a crash

Actual results:
tracing_service_impl.cc: Configured tracing, #sources:3, duration:0 ms, #buffers:1, total buffer size:25600 KB, total sessions:1
[21305:21305:1117/141541.854340:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

../../sandbox/linux/seccomp-bpf-helpers/sigsys_handlers.cc:**CRASHING**:seccomp-bpf failure in syscall 0230

Expected results:
Webpages load correctly and work immediately after loading

Additional info:
There is an Asciinema recording available at https://asciinema.org/a/MQ9pwezf4JFqg2dlrJRQf4vja. Note: the moment that the crash occurs, I was in the Chrome window visiting a URL which I knew would trigger the crash.
