Performance regression after upgrading from 1.11.5 to 1.11.7 #479
Description
Today I've tried to make minor change in my old sketch which uses Adafruit_SSD1331 on WeMos D1 Mini Lite with hardware SPI.
After making minor change to the code and flushing, I've noticed significant performance degradation of screen updates. This is reproducible with my custom code as well as LCDGFXDemo example.
I don't know what the reason is, but after downgrading Adafruit GFX Library to 1.11.5 issue was solved. I've tried version 1.11.7 - this is the first version in which issue appears. Issue is still present in 1.12.2.
