Issue descriptionObserved in Windows 7 x64 with: Chrome 66 dev Chrome 67 canary 1. install the attached extension 2. click its toolbar icon Expected: a) yellow background fills the entire width and b) scrollbar is shown Observed: in addition to a) and b) there is a red column on the right =================================================== Bisect info: 535635 (good) - 535645 (bad) https://chromium.googlesource.com/chromium/src/+log/e04a14f4..004f3b4b?pretty=fuller Suspecting r535636 = 96f85b68747a679ea1ac4cd05d6743ae5f7142b7 = https://crrev.com/c/857902 by skobes@chromium.org "Enable root layer scrolling." Landed in 66.0.3345.0 =================================================== Confirmed by disabling the suspected CL and observing the bug is gone: chrome --disable-blink-features=RootLayerScrolling =================================================== The popup is just a tall div, nothing fancy: <!DOCTYPE html> <html> <body style="width:200px; margin:0; background-color:red"> <div style="height:50vh; background-color:lightyellow"> In bad builds you'll see a red column on the right. </div> <div style="height:200vh; background-color:yellow"></div> </body> </html>

Able to reproduce the issue on Win-10 and Ubuntu 14.04 using chrome version #64.0.3282.186 and latest canary #67.0.3368.1. Issue is not seen in OS-mac. This is a non-regression issue as it is observed from M60 old builds. Hence, marking it as untriaged to get more inputs from dev team. Thanks...!!

Here's a workaround which might be useful for those who stumbles upon this bug:
html {
overflow: overlay;
}

This still reproduces. Ping for fix?
