Lilygo T5 V2: Lib GxEPD: The graphic display of x=0 y=0 (top left and right) is wrong with Platform IO, but correct with the Arduino IDE. What can do?
Please list the Arduino-ESP32 core version used in the Arduino IDE (Tools->Board->Board Manger → esp32), the version of the used GxEPD library in the Arduino IDE and a screenshot of the Tools menu.
So not GxEPD2 like shown in I can't load lib GxEPD2 and test examples - #3 by stoni99?
lib_deps =
zinggjm/GxEPD2 @ ^1.5.0
The GxEPD2 makes the same mistake under Platformio.
Well let’s equaliz the environments though or we’re comparing apples to oranges.
Set
lib_deps =
https://github.com/ZinggJM/GxEPD/archive/refs/tags/3.1.1.zip
and try to GxEPD/examples/GxEPD_Example at 3.1.1 · ZinggJM/GxEPD · GitHub running. Does it show the same error?

That is 3.1.3 though. Can you update to

This?:
I found something:
It has something to do with ‘display.setRotation(1);’ .
If I ‘display.setRotation(3);’ the display is correct.
With the Arduino IDE, however, both settings are correct.
