Possible bug in tabview handling

Hello,

I use lvgl v8.3.(1/2) with lv_port_pc_eclipse under linux.

In my app I have a dialog with 3 tabs in a tabview:

    tab_view  = lv_tabview_create(screen, LV_DIR_TOP, 32);
    tab_alarm = lv_tabview_add_tab(tab_view, "Alarms");
    tab_sta   = lv_tabview_add_tab(tab_view, "WiFi STA");
    tab_ap    = lv_tabview_add_tab(tab_view, "WiFi AP");
    lv_tabview_set_act(tab_view, 0, LV_ANIM_OFF);

Every time after changing an input field in the first tab, the lvgl library code also switches to an other tab, sometimes to the 2nd, sometimes to the 3rd!

How can I prevent this behavior?

Thanks in advance,
Michael
