Not observed any lines as in given screenshot in comment #0.

@ jlbvar19-- Could you please check in fresh chrome profile without any extensions and flags enabled and confirm us if we have missed any steps in reproducing the issue.

Thanks!

Does the effect depend on the window size? Could you please paste in the output of "chrome://gpu" to this bug report?

And finally, could you try Chrome Canary (which can be installed alongside the version you have) to see if the problem persists? We have had bugs due to GPU driver bugs that might include this case.

I believe this is a duplicate of the existing opacity issues. Marking it as such.

If I'm right, the fix was merged into Chrome 62.0.3202.48.
