How to solve collision between roller and other widgets when scrolling


Hey everyone here,I’ve used Roller recently to try some different show effects from widget List.And then I found a thing that Roller will collide with other widgets(e.g. brother widgets) when scrolling in their parent,just because Roller is rolling up or down while scrolling direction is left or right,and if I scroll obliquely,then collisions comes.
I haven’t find a good way to fix this yet.Is there anybody could give me a solution?

What LVGL version are you using?

released 8.3.0

Code to reproduce

/* My code here,quite simple example*/

    lv_obj_t *panel = lv_obj_create(lv_scr_act());
    lv_obj_t *obj_main = lv_obj_create(panel);
    lv_obj_t *obj_title = lv_label_create(obj_main);
    lv_obj_t *obj_other = lv_obj_create(panel);
    lv_obj_t *obj_roller = lv_roller_create(obj_other);

    // Size
    lv_obj_set_size(panel, 240, 240); // Screen size is 240*240
    lv_obj_set_size(obj_main, 240, 240);
    lv_obj_set_size(obj_other, 240, 240);
    // Text
    lv_label_set_text(obj_title, "Main Page");
    lv_roller_set_options(obj_roller, "First Item\n"
                                      "Seconde Item\n"
                                      "Third Item\n"
                                      "Fourth Item\n",

    // Location
    lv_obj_align_to(obj_other, obj_main, LV_ALIGN_OUT_RIGHT_TOP, 0, 0);

    // Styles
    lv_roller_set_visible_row_count(obj_roller, 3);
    lv_roller_set_selected(obj_roller, 0, LV_ANIM_OFF);
    lv_obj_set_style_text_color(obj_title, lv_color_white(), 0);
    lv_obj_set_style_text_color(obj_roller, lv_color_white(), LV_PART_SELECTED);
    lv_obj_set_style_text_color(obj_roller, lv_color_white(), 0);
    lv_obj_set_style_bg_color(obj_main, lv_color_black(), 0);
    lv_obj_set_style_bg_color(obj_other, lv_color_black(), 0);
    lv_obj_set_style_bg_color(obj_roller, lv_color_black(), 0);
    lv_obj_set_style_bg_color(obj_roller, lv_color_black(), LV_PART_SELECTED);
    lv_obj_set_style_bg_opa(obj_roller, LV_OPA_TRANSP, 0);
    lv_obj_set_style_bg_opa(obj_roller, LV_OPA_TRANSP, LV_PART_SELECTED);
    lv_obj_set_scrollbar_mode(panel, LV_SCROLLBAR_MODE_OFF);
    lv_obj_set_scroll_snap_x(panel, LV_SCROLL_SNAP_CENTER);

    // Flags
    lv_obj_add_flag(panel, LV_OBJ_FLAG_SCROLL_ONE);
    lv_obj_clear_flag(panel, LV_OBJ_FLAG_SCROLL_ELASTIC);

No buddy helps me? :cry:
I tried to use ‘lv_obj_add_state(obj,LV_STATE_DISABLED)’ when pressing roller to let it not roll,but it seems not working,roller still rolled when scrolled.
