First thanks for all the work you do, much appreciated.

I am using a ESP32 dev module with ILI9468 with FT6236 Capactive Touch screen

I have upgraded my library to 2.5.43 and I am suddenly getting an error message.

I am using the FT6236.h library for touch

Arduino IDE version 2,3,0 ESP32 version 3.0.0 ESP32 Wroom Dev Module SPI interface

The issue only occured once I upgraded the library, before that I have had no issues.

I am confused because if I run Free_Font_Demo.ino it runs OK. If I run my test sketch included below it runs OK

For my main project sketch it wouldn't compile at first time because I got an error with the line tft.loadFont(Calibri30), (a custom font I had made and used previously) as it said loadFont didn't exist. I assumed this was a library change so modded all those lines to: tft.setFreeFont(FSS24); as I couldn't work out how to get my font to work.

Once I had made that change I then got the TFT_WIDTH error. I can't understand how this could suddenly be not declared

User_setup.h included below is the same for all sketches.

I have been searching online for hours and got no closer so thought I shouold contact you directly.
