_v2od2o_@ in order to triage this issue could you please help us with the sample html test case, so that we can reproduce the scenario on our end. Thank You...

A reduced test case is attached. (The attached HTML in #4 consistently reproduces the issue, though it is not self contained as it depends on crucial CSS that comes from an external server) The good news is that it looks like it is already fixed in the current Chrome 57.0.2980.x canary. Requesting a reversed bisect to find the change that fixed it so it might get merged to Chrome 56 if necessary, since I heard there will not be a patch release for Chrome 55.

The promotion of fixed position to composited layers was reverted, no doubt fixing the problem.

I spoke too soon. We still need to find the cause.

Able to reproduce the issue on the reported version(55.0.2883.87/95) on Windows-10, Mac OS 10.12.2 and Linux Ubuntu 14.04. However the same is fixed in the latest canary(57.0.2982.0) and the latest beta(56.0.2924.59). Reverse bisect result: ====================== Last bad build: 56.0.2899.0 First good build: 56.0.2900.0 Changelog: ========== https://chromium.googlesource.com/chromium/src/+log/30188759b05f607fd5a664bc95e78159b91340bf..a4969c67949640d4a7fbe2a2ea91cb4506aaa218 Looks to be fixed by https://codereview.chromium.org/2436283002. wangxianzhu@: Could you please take a look and confirm if the change is related to this. Note: No merge required here as this is already fixed in Beta channel well.
