Jim, can you investigate what's going on here ?
(I'm fairly sure it's related to bug 1187153 too).

Those 2 bugs used to happen on Windows 8 and Windows 7 as well when custom caption buttons were used. May as well be related to the chromemargin.

I haven't checked on Win 10, but the same issue occured on Win 8 and 7 (e10s enabled or not) when custom caption buttons were used (via an userstyle)

Hmm, I can't reproduce on Win7 using the following str:

1) set your home page to google.com and specify it should be loaded for new windows through options
2) using ctrl-t, open twenty windows

result: window content bounds looked fine in all new windows.

You need custom caption buttons. Try this userstyle : https://userstyles.org/styles/104729/devfox
(Enable the custom window frame option).
You may also need to reduce the chromemargin.
P4 based on this not being a default config nor a regression in Windows 10, but it bothers me a bit more than a normal P4 because the cause-and-effect is not at all going to be obvious to a user who has done this.
Priority: -- → P4

This is now the default config on Windows 10, we use the custom caption buttons, which causes this bug.
This is on 100% DPI too. Although, since this is hard to reproduce I agree about the priority.
