I’m having an issue where my GUI crashes due to the wrong object being deleted when I call
lv_obj_del. For more information, it is happening in the Visual Studio simulator, I haven’t been able to discover if it’s an LVGL issue or Visual Studio issue, but I’m curious if anyone has experienced this before.
I have a msgbox object I’m using as a popup to change some menus, before the msgbox is created I create an object the size of the screen, make it pure black, and the set the opacity low so it grays out the background. Like this:
Now when a user selects a button or presses exit it’ll call the
lv_msgbox_close function, which I’ve slightly modified to check if the background shader exists and delete it too. We can see all is fine when this happens:

But when I step inside the
The object pointer is now changed to that is suppose to be “lcd_ui.textarea”, when we step out of the
lv_obj_del function, we can see that it was in fact “lcd_ui.textarea” that was deleted:
I’m at a total loss on how this is happening. I’m going to try to revert to an older version of visual studio and see if it fixes this issue.
