Public bug reported:
Chrome, Chromium, Slack, Zoom, and VS Code all exhibit extreme
flickering, ghosting, screen tearing, and general artifacting while
hardware acceleration is enabled. Disabling hardware accelerations in
those applications resolved this issue.
This only started after I ran the following:
```
$ sudo ppa-purge ppa:oibaf/graphics-drivers
$ sudo apt-get install --install-recommends linux-generic-hwe-18.04
xserver-xorg-hwe-18.04
```
Therefore, I'm confident that the issue has something to do either one
of those packages. However, I'm not entirely sure if the issue
originates in `linux-generic-hwe-18.04` or `xserver-xorg-hwe-18.04`.
I don't know what other diagnostic information to include, but I can
continuously provide information in comments as requested.
