Your behavior is valid. But me and my collegues have invalid behavior as in my screenshot. Div is moving because we can see bug only after moving. We tested it in clear new chromium too. It has the same problem. You should try it with another hardware. It isn't related to windows version(we have different with same bug).

Looks more like paint than font. Alloe me to label Paint, but please re-assign if this looks incorrect.

pdr@, could you mind to advice what is the most possible cause?
There are any number oif potential blame patches. Here are just a few. I'll try bisecting again.

I could not reproduce with Windows 10 HighDPI (125%) with Version 61.0.3163.59 (Official Build) beta (64-bit).

Given M-61 is rolling out any day now, this seems like we should wait.

akiff13@, do you have the same problem with Chrome Canary?

Can you paste in the results from visiting chrome://gpu for a computer that works and one that does not?

Just got to this bug after my vacation. I agree that this does not trivially reproduce, but it could definitely be due to a difference in our hardware.

As Stephen noted, can you try with Chrome Canary (or re-try with Chrome 61 which should be out now)? If you are still able to reproduce, please go to chrome://gpu, file>save as, and attach the file here.

Testing team: does the repro that you found in comment 5 still work on Canary,
or has it since been fixed?

jmukthavaram, can you please post your chrome://gpu information?

I'm not able to reproduce this locally but I think it is likely hardware-specific.

Because this only reproduces on some hardware, I suspect this is cc and not paint. Could also be the Skia roll. I tried to reproduce on both low and high dpi on windows.

Please also try with --disable-d3d11 . Does that fix it?

@robertphillips: this appears to a duplicate of  issue 755871 , can you confirm?
It seems unlikely to be a duplicate of  crbug.com/755871 . That bug is driven by an ancient Intel driver bug. This CL seems reproducible on Windows 10.

akiff13@, is this still happening with Chrome 61? What happens if you disable d3d11 as requested in comment #15?

Testing team: please post the contents of about:gpu and more information about
the specific device.

As per comment #18 attaching GPU details. I have Windows-10 Dell Precision M3800 (HiDPI).

Given the symptoms (i.e., noise on Angle/D3D11) I suspect this is a duplicate of  crbug.com/768134 . 

I have never been able to repro this bug locally however. Could someone who can repro the problem consistently see if it still repros in the 63.0.3234.0 (or above) Canary? Unfortunately, the fix is not yet in any available Beta.
Verified this issue on Windows-10 using chrome latest canary #63.0.3237.7 and latest beta #62.0.3202.52, Observed no noise in the animation using the test case provided in the original comment and confirming this issue got fixed and working as expected.

Thanks!
