Common values for scaling are in the 1.0 to 1.5 region, so I'm not particularly surprised you get issues at 1.7 and over. I don't think there's anything you or I can do about this here, it would need a code fix.

Best to post in the Bug Reports forum with some screenshots illustrating the problem, plus these files:

DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file.

Documents/Paradox/Stellaris/settings.txt and pdx_settings.txt .
Documents/Paradox/Stellaris/logs/system.log

Good luck with that!
