Landed in 68.0.3421.0

Meanwhile you can "fix" it temporarily by disabling chrome://flags/#enable-gpu-rasterization

The "fix" helps just a bit; for example, text in omnibox is still screwed up.

I had the same issue, upgrading my Nvidia driver fixed this

Can confirm that disabling gpu rasterization fixes most, but not all rendering issues. Particularly first characters in HTMLElements tend to render incorrectly.

Updating display drivers didn't change anything for me.
The bug probably manifests differently depending on hardware.

chrome://gpu is different for "Driver Vulkan API version":
r556176: Vulkan API 1.1.0
r556188: Not supported

Still broken in Chrome Version 68.0.3422.0 (Official Build) canary (64-bit)

Duh, of course it's still broken. Developers don't work on weekends. When the fix lands you'll see a message generated by the commit bot. Don't get your hopes high though, it may take a week or two.

 Issue 840146  has been merged into this issue.

please fix this!!!

The problem got much much better once I updated my NVIDIA display driver to the latest version (397.31 release date: 04/25/2018).

I still see flickering fonts when typing though.

Can reproduce on Windows 10 1709. 
The font looks really weird and sometimes some characters fail to render. When character fail to render and you try to select the text, the tab crashes. 

Can confirm this happens on newest canary. My version:
Version 68.0.3422.0 (Official Build) canary (64-bit)

On newest Chrome everything seems to be working fine. My version:
Version 66.0.3359.139 (Official Build) (64-bit)

That bug happens with Intel HD Graphics and Nvidia.

bungeman: can you take a look?

An internal bisect confirms this is the Skia roll. And "Avoid drawing BW clipped color glyphs many times." is my best guess.

Revision 556183 is [(g)ood/(b)ad/(r)etry/(u)nknown/(s)tdout/(q)uit]: g
You are probably looking for a change made after 556183 (known good), but no later than 556184 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspect as some perf builds might get missing due to failure.

I suppose bd66caa, 91840ab or b9a1e68 are remote possibilities.

revert nvidia driver to early version fixed the problem for a while but after restart, it comes back

 Issue 840210  has been merged into this issue.

Note the text in the profile menu is glitching in a slightly different way. That text uses a blur/shadow, which also suggests https://skia.googlesource.com/skia.git/+/bd66caa

fixes this for me.

So I guess it's that initializer...

Chromium sheriff here.
That skia roll also caused a lot of layout test failures on windows:

https://ci.chromium.org/buildbot/chromium.webkit/WebKit%20Win7/63854
https://ci.chromium.org/buildbot/chromium.webkit/WebKit%20Win10/34481
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20Tests%20%28dbg%29%281%29/68856
(see "layout_test_results" link)

I'm going to revert the skia roll.

3423 is based on r556364 so it doesn't have the fix. I guess it'll be released in Canary 68.0.3424.0

Started yesterday for me, bug only on CANARY version.
