Titlebar is black

[m.losinno]

Hi @all

Sometimes the title bar is completely black.

This usually happens when I’ve minimized the application and then reopen it.

What could be the problem?

Thanks!

What version of Windows?
Is your app manifested?

After the window is open, can you change the text of the title and does it appear?

0{prop:Text} = 'Some New Window Title Text'

It might be a window acceleration issue.
Settings > System > Display > Graphics > Advanced graphics settings, where you toggle the HAGS switch and restart your PC.

I have Windows11.
Yes, the app has a manifest, but a simple one.
When the window loses focus it looks as it should.
The acceleration is on, I had this already off.
Do I need something like API “RefreshOnFocus”?

If its happening to only the one window you have reported, I would look at the code generation. Perhaps even paste the code here and the manifest file.

If its happening to all windows, I would look at Accent colours.

It happens with every window, but only with the topmost one.

I’ll take a look at the AccentColors thing.

Thanks!
