Hi @lpereira98

I have never seen this before and your Apps seems quite simple. Can you please perform the following?

1. Test it on any other PC
2. Test it without MahApps but every thing else the same. Do have also trouble?
3. If 1 and 2 are done and you still have trouble, please share your entire sample via GitHub. Maybe there is something in the code behind which triggers this behavior.

Happy coding
Tim

Hi @timunie

It's definitely some problem about my PC, this app runs like a charm in any other PC. And even without Metro, i still have problems, i just haven't noticed before.
I can't figure it out, my PC definitely satisfies WPF prerequisites.
Any idea of what can be the problem? My graphic drives are updated, windows is updated 🤷‍♂️

@lpereira98 I have no idea and this is also not the right place to discuss this. Please close the issue as it is nothing we can solve. 🙏 Thank you
