The upcoming 0.70b11 has optimizations on the text rendering engine (from 3 to 16 times faster).
This should fix the big font rendering slow down due RA8875 hardware limitations.
Another nice unique feature it's the ability to write render Text with background transparent,
I haved received some pressure from users for change the current font scheme with a popular GLCDFontCreator2 or other library one but I will not because those schemes are too limited and I will never use again an offsetted font (one big array with glyph defined as offset).
The current scheme it's much better, it's easy to change a font or erase a single glyph from file but most important it's rle compressor compatible and perfectly fit in a ROM so in the future user can burn a ROM or EEPROM or whatever with his font library and free-up the MCU resources.

Here's in brief the technical notes about the new rendering engine... https://github.com/sumotoy/RA8875/wiki/Text-Render-technical-notes...
