Hi kai-a,

This issue is fixed in v1.4.0 which will be released soon, as a quick fix, please do the following change and try again.

lv_textarea_set_text(ui->screen_1_ta_1,"Hello World");
if (g_kb == NULL)
{
g_kb = lv_keyboard_create(ui->screen_1);
lv_obj_add_event_cb(g_kb, kb_event_cb, LV_EVENT_ALL, NULL);
lv_obj_add_flag(g_kb, LV_OBJ_FLAG_HIDDEN);
}
lv_keyboard_set_textarea(g_kb, ui->screen_1_ta_1);

lv_textarea_set_text(ui->screen_1_ta_1,"Hello World");
g_kb = lv_keyboard_create(ui->screen_1);
lv_obj_add_event_cb(g_kb, kb_event_cb, LV_EVENT_ALL, NULL);
lv_obj_add_flag(g_kb, LV_OBJ_FLAG_HIDDEN);
