Chromium Browser - Bottom Scroll Bar Flashing On/Off Continually

[DiagonalArg]

Since the update which included the kernel update from 4.4.0-92 to 4.4.0-93, the bottom scroll bar on chromium is continually flashing on/off, even when the screen is large enough (horizontally) for the page (so usually there wouldn't be a scroll bar) and even when there's no activity in the browser (I just let it sit for a while and it continually flashes). The rate seems a bit random. This is happening in both regular and incognito mode.

When running apport -p chromium-browser <this-bug-#>, I get this error in the terminal (and end up with a popup screen asking me to send bug info to the developers):

ERROR: hook /usr/share/apport/package-hooks/chromium-browser.py crashed:

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Do you still see a problem related to the one that you reported using Chromium 73, the currently supported version of Chromium in Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
