dmomo996@ Thanks for the issue. Able to reproduce this issue on Windows 10 on the reported version 69.0.3497.12 and the latest Canary 70.0.3506.0 as per the original comment. Attached is the chrome://gpu details. Note: Issue is not reproducible on Windows 10 HP Elitebook laptop, Mac OS 10.13.3 and Ubuntu 17.10. Bisect Information: =================== Good Build : 69.0.3444.0 (Revision:562313) Bad Build : 69.0.3445.0 (Revision:562690) Tried running the per-revision Bisect script, but 'Failure: [Errno 1] _ssl.c:507: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed.' error was coming up. Hence below is the Changelog URL from omahaproxy: https://chromium.googlesource.com/chromium/src/+log/69.0.3444.0..69.0.3445.0?pretty=fuller&n=10000 Unable to find the right suspect from the above Changelog URL. Hence tentatively adding 'Internals>GPU>VendorSpecific' and 'Internals>Compositing>Rasterization' components to look into the issue and help in further triaging. Adding 'ReleaseBlock-Stable' label as this is a recent regression. Please feel free to remove if it is not applicable. Thanks..

not sure it's vendor specific victor: who should take a look with this zero-copy rasterizer bug?

This is an experimental flag setting, and the zero copy mode is not supported on Windows so please don't set this option. To reporter: The setting may have worked in the past because it was ignored. Please reset experimental your flag settings to defaults.

Suspecting this change may have affected handling of the flag. https://chromium.googlesource.com/chromium/src/+/57baa774bfecb02345e30c95ad8a6ddc3e6a0092
