Description
I'm using a 1.8TFT SPI 128x160 display.
I also use develop/lvgl_7.11.0_idf_5.0
for lvgl_esp32_drivers and v7.11.0
for lvgl.
Describe the issue
I use the following connections:
- PIN LED to 3.3V
- PIN SCK to GPIO14
- PIN SDA to GPIO13
- PIN A0 to GPIO2
- PIN RESET to GPIO4
- PIN CS to GPIO15
- PIN GND to ground
- PIN VCC to 5V
Running the example I don't see the correct result on the screen.
Code to reproduce the issue
The given example with the following sdkconfig where I matched the pins and the display resolution
Expected Results
The windows shown in the example
Actual Results
I see this picture on the screen with fluctuations of the content but it doesn't work.
In the serial monitor I don't notice anything "strange":

Compilation warnings/errors (if available)
Yes, some warnings at the bottom of the log.
lvgl_log_build.txt
If possible, copy the compilation log into a file and attach it here
- Is this display supported?
- If yes, what kind of error I'm encountering?
- Is there a way to fix it?
Thank you for your help
