LogSlate: Warning: FontCache flush requested. Reason: Large atlases out of space; 2/1 Textures;

Hi there.

What is the best way to force a flush of the font cache?
Calling the Cvar Slate.FlushFontCache 1 ?

We have noticed that in-game, 2 pages seems to be enough… If the cache hasn’t been pre-filled with junk in the pre-game main-menu.

It seems that if even if we expanded the initial pages to
Slate.MaxFontAtlasPagesBeforeFlush=2
, we would still run into at-least one flush in-game, due to the cache not being cleared beforehand.

Any suggestions here?
I will to look into the cache contents via Slate.DumpFontCacheStats=true shortly.
