I couldn't reproduce on M-60 on Linux or Win 10. I'll try bisecting to see if this was an issue fixed since M-59.

I cannot reproduce on 59.0.3071.86 on linux, nor M-60 on Win 10.

Could you please try Chrome Canary to see if the problem persists? If so, does it depend on window size or DPI or anything like that?

On Version 59.0.3071.109 (official build) (64 bits) it shows the glitches when the window is not too small (> 300px), and regardless of the zoom.

However when in mobile emulation mode, it's working correctly.

I also tried on the same version on another computer with no issue.
Major difference is that it's using a NVIDIA graphic adapter (the glitched one is using a intel graphic adapter).


My tests on Canary with intel graphic also show the glitches:
Version 61.0.3137.0 (official build) canary (64 bits)

I attached 2 screenshots of the issue.

Thanks, that indicates a GPU issue most likely. Please go to chrome::/gpu and paste the output here. The GPU team may be able to help.
