ESP32, TFT_eSPI, ILI9488, and FT6236 CTP Configuration Problem

[GeorgeIoak]

Describe the bug

Adding GUIslice to working sketch yields compile errors, endless reboot, or incorrect screen draw depending on different changes and checking in Arduino IDE or PlatformIO. I tried several experiments and configurations but never was able to get an example code to run properly yet the TFT_eSPI tests work as expected with no changes required other than the required configuration.

Device hardware

• MCU: ESP32
• Display with link: BuyDisplay ILI9344 w/ FT6236 CTP, https://www.buydisplay.com/serial-spi-3-5-inch-tft-lcd-module-in-320x480-optl-touchscreen-ili9488
• GUIslice config selected: configs/esp-tftespi-default-ft6206.h

Please confirm whether:

• Display works correctly with standalone display driver library examples (eg. TFT_eSPI graphicstest, Adafruit graphicstest, etc.) without GUIslice: Display and CTP work correctly with just TFT_eSPI in both Arduino IDE and PlatformIO
• Touch works correctly with standalone touch library examples without GUIslice: Yes it does

Expected behavior

A successful compile without having to uncomment flags (in PlatformIO) and example code run properly
