On the contrary, I have a rather positive experience in developing a project using these displays. There is some slowness when opening windows with many elements (40-90 widgets in a window) and not everything works as we would like, but in general, all my interface tasks have been completed. 15 windows with workflow and different menus, pop-up warning windows, some windows have 40-90 active widgets – everything works fine 🙂
I’m afraid the new displays no longer work with Tools 2019. Although only official support can say for sure.
If a progress bar appears during loading, but there are no inscriptions, then as an assumption, an incorrect project was loaded into the display, which included an incorrect (for this display) “default” font. When loading new project, the display shows all texts using this “default” font that was loaded with the previous project.
