Do you mean that the glimpse is the background was initially light gray (0:07) then turned into white (0:09) then into light gray (0:14) ? I'm not sure if I observed it locally because it always happens too fast. How did you get the result that the glimpse happens slowly as shown in the video?

I compared traces of r451400 [expected] and r451600 [actual], and found that in [expected] we delay the first paint after executing the javascript that sets up the UI, while in [actual] we paint the white background before executing the javascript. Based on the trace behavior, I bisected to https://chromium.googlesource.com/chromium/src/+/2d84fd7e2cdb13ae3fbe894319ef828febd14f0e. The behavior change is actually caused by change of the chrome://settings page itself, so this is not a rendering regression.
