Deleting unused static textures leads to crash

[tsucres]

Version of Dear PyGui

Version: 1.0.2
Operating System: Ubuntu 20.04

My Issue/Question

I'd like to delete unused static textures. However, calling dpg.delete_item(texture_id) systematically crashes the app.

Maybe there is another, better, way of deleting textures I'm not aware of?

Or maybe they're supposed to be freed automatically when the reference count == 0? But in that case, I would expect them to disappear from the registry inspector.

To Reproduce

Run the code bellow and click on the button.

Expected behavior

I would expect

1. the app not to crash,
2. the old texture to be freed,
3. the new image/texture to be shown in the window and
4. a single texture being listed in the registry.

Standalone, minimal, complete and verifiable example

import dearpygui.dearpygui as dpg

    dpg.create_context()
    dpg.create_viewport()
    dpg.setup_dearpygui()

    texture_tag = None
    img_item_id = None
    texture_registry_id = "__texture_registry" 
    
    def btn_callback(sender, appdata):
        global texture_tag

        # Maybe trying to delete a texture that is still used in the image item is not a good idea... so let's deleting it later...
        texture_to_delete_tag = texture_tag 
        
        s = np.random.randint(100, 200) # I want to load a completely different image, which might have a different size
        new_img = np.random.random([s, s, 4]).astype(np.float32)
        texture_tag = dpg.add_static_texture(s, s, new_img, parent=texture_registry_id)
        dpg.configure_item(img_item_id, texture_tag=texture_tag)
        if texture_to_delete_tag is not None: # Here the old texture shouldn't be used by anything, we should be able to delete it?
            # By commenting the following line, the program runs fine. But the textures seem to accumulate in the registry.
            dpg.delete_item(texture_to_delete_tag) # CRASH!
            
    with dpg.texture_registry(show=True, tag=texture_registry_id):
        texture_tag = dpg.add_static_texture(100, 100, np.random.random([100, 100, 4]).astype(np.float32), parent=texture_registry_id)
    with dpg.window(label="issue"):
        dpg.add_button(label="Press me", callback=btn_callback)
        img_item_id = dpg.add_image(texture_tag=texture_tag)

    dpg.show_viewport()
    dpg.start_dearpygui()
    dpg.destroy_context()

Hi, this doesn't seem to be happening on windows so I will have to check ubuntu tonight.

This app demonstrates how to load and unload images textures.
