Having an issue where when using Firefox on Windows 7 Pro via a Windows remote desktop connection, there are random issues with page rendering on pages that were already open prior to the RDP connection. Refreshing a page does not correct it and it's completely random on which page/tab it occurs on. Completely exiting FF and relaunching fixes.

This is happening on completely different computer systems (Work vs Home) and started on FF v56 and continued into v57. Only thing common is the host computer is Win 7 Pro 64bit. The connecting computer/platform doesn't seem to make a difference.
