In these cases, I would assume it is more likely to be a browser bug than a CSS bug.
Probably a hardware acceleration issue (I assume remote debugging uses software rendering). You can verify by using software rendering in Android (I am not sure how, maybe there is a WebView setting).
You can search
crbug.com for an existing issue and star it. If you cannot find one, file a new issue using the "New issue" link on the same page.
Please, do not add a "+1" or "Me too" or "Confirmed" (or similar) comment. It just wastes the time of Chrome engineers and sends unnecessary e-mails to all of the people who starred the issue.
You can reply with a link to the found or created issue and might get triaged (and fixed) faster.
