Touch works well with GT911, unreliable and slow button response with FT5446 controller. Multi-touch issue?

I have a custom ESP32-S3 board with a 5 inch 800 x 480 RGB display using an Arduino environment. Screen is using buttons and sliders. Original board used a GT911 touch controller.
This worked flawlessly using Arduino GFX and TASM911 driver. New display uses a FT5446 touch screen controller. Display works fine, but touches are not registered reliably and slowly.

Before posting

  • Get familiar with Markdown to format and structure your post
  • Be sure to update lvgl from the latest version from the master branch.
  • Be sure you have checked the FAQ and read the relevant part of the documentation.
  • If applicable use the Simulator to eliminate hardware related issues.

Description

What MCU/Processor/Board and compiler are you using?

What LVGL version are you using?

What do you want to achieve?

What have you tried so far?

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

If possible, add screenshots and/or videos about the current state.

More – LVGL 8.
I need to have the buttons and sliders work smoothly and reliably as they did with the GT911 controller.
I have used i2C decoding to see the response from the controller and ESP32. What should I see from the Ft5446 when I tap a button? I see a “Contact” followed by a “UP” response, but his does not register as a tap.
I thought I read somewhere that LVGL uses polling of the touch screen and not interrupts.
The GT911 did not use interrupts but the FT5446 does. I notice that the FT5446 generates a interrupt every 10ms when button is pressed and the LVGL code scans every 30ms. It does not catch every interrupt. I’ve also turned of the periodic interrupts on the FT5446 and then tried falling and interrupt change triggering. Still no joy.

I’m using the FT6X36 drivers and touch.h.
