Extremely low quality text

[WeevilEye]

I find that text in all text boxes and menus is rendering at extremely low quality. The map looks fine, but all text is difficult to read. I will attach a screenshot of my graphics settings, which will also show the issue as the menu itself is difficult to read.
I have tried different screen resolutions and different GUI scaling. The problem persists at all settings. Any help would be appreciated!

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 then attach that file here.

From your Documents/Paradox/CK3/logs/ folder, attach system.log , error.log
