@phistr Hi!

  • It is over complicated: SystemText and Text are in fact two separate rendering pipelines.
  • It is slow: SystemText caches rendered text on per line basis, so each new line involves calls to Canvas.drawText which is slow.
  • SystemText render text with visible artifacts ( look close at bottom of 'у' glyph for example )
