console.print(Panel(str(os.environ), title='[white on blue]Title[/white on blue]', style=Style(color="white", bgcolor="blue")))
Filling the title with a separate color does not solve the problem (it is also not completely filled).

Correct result (1 screen, completely painted over header). Workaround is to use rich v 13.0.1.
Is there a fix planned?

@willmcgugan
can you tell me something useful about the open issue that hasn't been updated for 5 months. Because of this problem, I'm forced not to update rich in my projects since version 13.0.1.

@snooppr I'm not Will, but perhaps as a workaround in the meantime you could try setting the border_style to the same background as the panel? For example:

from rich.console import Console
from rich.panel import Panel
from rich.style import Style

console = Console()
console.print(
    Panel(
        "Content",
        title="[bold white]Title[/bold white]",
        style=Style(color="white", bgcolor="blue"),
        border_style=Style(bgcolor="blue"),
    )
)

It looks like there's a history of issues related to the panel title style, so any fix for this issue should be careful not to cause any regressions...

@TomJGooding
Thanks, the "border_style" hack solves the problem. Works in both old and new versions of rich.

I hope we solved your problem.
