I love the new PM pop-up and had no problems with it on my larger work monitor this morning, but at home on my little windows laptop screen I have to zoom out to see all the buttons:
- 100% zoom
- 80% zoom
Due to my desk setup I do currently have my overall display scale set to 150% rather than the recommended 125%. Switching it back to 125% fixed the problem when my browser is at 100% zoom. So, my setup may be just unique enough that you may decide it's not worth fiddling with the responsive settings, but I thought I'd mention it since smaller laptop screens may have the same issue!
Chrome, and according to whatismyresolution.com, my screen's at 1123x632.
