I recently installed ArcGIS Desktop 10.6 (Windows 7, 64-bit) and it's working fine except it seems to be displaying a little funkily (see attached screenshot), which I think may have to do with the screen resolution? My screen resolution is set at 1920 x 1080.
As you can see in the attached screenshot, when the ArcMap 10.6 window is maximized, it overfills the screen slightly. Plus, the menu dropdowns appear misaligned with the respective menu items. This isn't shown in the attached screenshot, but the hover tips in the table of contents also appear misaligned (e.g., fairly far above where they should be).
There are not similar issues with ArcCatalog, but AcrScene is doing the same wonky things as ArcMap.
Any ideas on what's going on here and how to resolve it will be much appreciated.
