It works here, so try to update.
(That problem belongs to another build)

I have DPI = 125% because of a 4K monitor. Setting it to 100% (default) fixes the issue. Of course this is not a solution for me but at least I know where it comes from now.

the pop up search-copy is not working here, not responsive.

here neither, annoying.

Same issue on Windows 7.

Version: 45.0.2552.634
