Confirmed Windows 10 Home 64-bit en-US with

Version: 6.4.0.0.alpha0+ (x86)
Build ID: 2ef2c031ce9ec730b13fca8bca808f382aab5fe4
CPU threads: 4; OS: Windows 10.0; UI render: GL; VCL: win; 
Locale: en-US (en_US); UI-Language: en-US
Calc: threaded

Default GDI rendering also affected.

As compared to 100% scaling (my default) moving to 125%, or 150% the font rendering has gotten very 'fuzzy'

Seems recent issue, not sure when as I don't scale os/DE UI above 100% often.

Unfortunately, both Roman and myself get nonsensical results when bibisecting this!
