Graphical corruption in M62

Project Member Reported by sande...@chromium.org, Sep 6 2017

Issue description

Chrome Version: 62.0.3198.0 (Official Build) dev (64-bit)
OS: Linux (gUbuntu)

What steps will reproduce the problem?
(1) Navigate to some Chromium code in Code Search. (eg. https://cs.chromium.org/chromium/src/base/time/time.h?q=time.h)
(2) Expose additional tiles after loading completes. (In the screenshots, I did this by closing the nav panel. Scrolling also works if the page is wide enough.)

What is the expected result?

Whitespace and code is rendered normally.

What happens instead?

Garbage is rendered. In some cases, this garbage can also appear while scrolling down, in which case it becomes really hard to use the web page.

This reproduces reliably for me in the Chromium code search on my gUbuntu workstation. Other pages experience corruption as well, but not as reliably. Swapping out the Quadro K600 for a 950Ti did not help. Disabling hardware accelerating rendering did not help.

Chrome 61.0.3163.79 does not have the same issue on my workstation.
