--- Comment #11 from V Stuart Foote <vstuart.foote at utsa.edu> ---
So, in addition to DirectWrite Direct2D rendering quality, there is also a
noticeable performance impact from refactored font handling at 5.3 on Windows
builds. 

Rendering multiple text objects--especially cells in a Calc sheet when
scrolling or resizing [1][2]--has slowed with default HA or CPU only rendering,
though still reasonable with OpenGL.

Likely requires additional font caching of some kind.
