TextBlock does not show up

[ItalicIntegral]

When trying to do the exercises in the orbtk book, I am able to compile the first example orbtk_hello. The window title shows up but the TextBlock contents do not show up. I tried changing the background but that did not resolve the issue. I then tried to use the orbtk_template code. Again, it compiled, title showed up but not the TextBlock.

Desktop (please complete the following information):

• OS: PopOs
• Browser Firefox 105.0.1
