Dear @dmazzella,
LVGL v9 fix has been merged. It will be available in the next Core release.
Remember to update also the Arduino_GigaDisplayTouch library to version 1.0.1.

Hi @dmazzella ,
thanks for the heads up! I tried a quick 'n dirty porting, basic functionality is in place (see here and here ) but there's still work to be done due to the deprecation of sw_rotation
flag (so Giga display shield only works in portrait mode).
@kisvegabor could you provide some insights on how the new lv_draw_sw_rotate
API is supposed to work? The original draw_buf_rotate
implementation is quite more sensitive on RAM (and transparent).
@leonardocavagnis since the plan is to release the core next week I'd proceed with adding an #error
if LVGL_VERSION_MAJOR
is 9
, so at least there's a clean way to avoid the issues flood.

Hi @facchinm,

It really required 2 separate source and destination buffers now. Note that the "original draw_buf_rotate implementation" from LVGL v8 was dynamically allocating a smaller temporary buffer for rotation.
The current implementation is
- faster and cleaner
- more explicit (there is no hidden allocation)
- more flexible as you can provide any kind of destination buffer
- you can rotate the source buffer line by line, so you need only one line for the destination buffer.
