FastLED Flexible Text Message Class requires LEDMatrix Class

Is this library slow? Seems like it from my testing. #32

I am using the ESP8266 so maybe the ESP32 would be more adequate but I was getting serious framerate drops using the text over top a noise pattern. This library seems to only work well when no other patterns are shown.

If anyone can suggest an alternative I would greatly appreciate it!

It's also entirely possible I am using it wrong. I am basically using the first example and then using FastLED's blend() to merge it with another CRGB[] driven by inoise8().

Why did you not use the BackgroundMode function? It allows you to leave the background untouched so only the letter pixels are rendered to the LEDs. Take a look at the Function List in the Wiki. I am not familiar with the inoise8() you refer to but I presume it takes a CRGB array pointer and a size so in my exmaple1 the pointer of the Matrix is leds[0] and the number of leds is leds.Size(). Do the inoise8() call before calling the UpdateText and in your setup use the SetBackgroundMode(BACKGND_LEAVE) I think the Blend function would probably be slowing you down as it does some complex colour blending.
